OK here's the fifth of the positional break downs, I have altered the content a bit on this one, again it takes it's basis from 'Chelsea: The Transfer Market Story 2013 and beyond' .
A good modern libero is something we really need a player who has some defensive awareness, good reading of the game, a large range of passing and the ability to dictate play';http://www.sabotagetimes.com/...e-rise-of-the-modern-libero/
We need a directing player in the Modric/Sahin mold, a player who can direct play around the park. central midfielders our youth ranks are stacked with them (Lamisha Musonda, Tika Musonda, Charly Musonda, John Swift, Lewis Baker, Ruben Loftus-Cheek, Victorien Angban, Anjur Osmanovic and Isak Ssewankambo and that's not mentioning Josh MacEachran, Kevin de Bruyne, Oscar and Ramires - also to be fair for many of the youngsters they are also quite apt in other positions and may ultimately turn out for the senior team in other roles), but we could still use at least one more in the senior squad.
There is a long list of potential options - partially because defining the difference between roles of midfielders can get a bit difficult and also because there are lots of good and seemingly available players in these positions.
- Joao Moutinho (strongly linked to Tottenham, I have a seeking suspicion Barca and Man U are still interested as well, our interest still exists, but Porto caused enough trouble with Hulk)
-Paulo Henrique Ganso (again more an attacker, has recently moved to Sao Paulo, with his injury woes he's more a gamble than Oscar and he wants a move to AC Milan, but you can't deny his quality)
-Felipe Anderson (the 'Brazilian Modric' that is really enough said, enjoying great times at Santos since Ganso's move to Sau Paulo, wanted by numerous European clubs, would bring the added Santos association which would link us up with Neymar, Victor Andrade, Leandrinho and Gabriel Barbosa)
-Thiago Alcantara (doubtful to leave Barca unless the Spanish economy tanks further and the dodgy support the Catalan govt gives Barca becomes untenable, awesome prospect we've had our eyes on for years, played with Romeu at Barca)
-Yohan Cabaye (a star at Newcastle, not sure he'd be one at Chelsea, but he wouldn't embarrass himself either)
-Moussa Dembele (again more an attacker, a target before he signed for Fulham and then Spurs, wanted by Man U and Real Madrid, Belgian...which is a plus these days - speaking of Belgians, the younger ones in this case particularly...)
-Dennis Praet (an attacking midfielder who Anderlecht took from the Genk academy a couple of years ago. He’s won prizes in various tournaments and is likened to Belgian legend Enzo Scifo in his style of play)
- Hannes van der Bruggen (a real find, a player who can cover all positions in midfield and yet another player on whom there are big wraps)
- Massimo Bruno (showed his potential in Anderlecht's game last week to ensure their passage to the UCL group stage)
- Umberto Carvalho dos Santos (similar to Man U's Andreas Hoelgebaum Pereira, a Belgian-Brazilian midfield maestro)
-Steven Defour (Porto problems again and he's not exactly lived up to his potential thus far, the fact he could still be considered shows how much potential he has, Belgian)
-Ander Herrera (one of the great Bilbao generation, had a poor Olympic campaign, poor man's Thiago Alcantara, but that still means he's great, could also help with drawing some of the other fine Basque talent currently on offer to the Bridge, particularly Iker Muniain, Iñigo Ruiz de Galarreta, Jon Aurtenetxe, Jonás Ramalho, Fernando Amorebieta and Markel Susaeta )
-Iñigo Ruiz de Galarreta (not the man to solve our issues now, but a man with a big future and one we should be looking at closely, our Mancunian rivals certainly are)
-Radja Nianggolan (serious talent, but probably better suited to Italy than England, I doubt some of the hype around him too, an option but well down my list, hasn't taken the opportunity to move to a bigger club the last two transfer windows - Man City and Juventus were interested...I'm not sure if this says something or not)
-Sergi Roberto (young, but a huge talent, probably hard to draw him away from Barca, would be awesome if we could though, he's got a big future - several of his Barca teammates also deserve a look in - Sergi Samper, and Fernando Quesada)
-Ilkay Gündoğan (a rising German star, I used to be a doubter but his performances this season have won me over he'd make a fine addition, will be difficult to move from Dortmund unless the current speculation about Klopp being considered for management is accurate...which i strongly doubt - teammates of Gündoğan; Moritz Leitner, Kevin Großkreutz, Ivan Perisic, Leonardo Bittencourt all also deserve some consideration, although both Perisic and Bittencourt are probably better a bit further forward)
-Fernando Lucas (Huge talk about this lad, Gremio's latest star prospect, I'd love to see him brought in he's one of my personal favourites, Inter and Roma are also after him)
-Granit Xhaka (only recently moved to Borussia Mochengladbach but is already attracting suitors to take him away from the the Rhineland, a more complete option than some of the others on the list)
-Ole Selnæs and Markus Henriksen (a pair of impressive young Norwegian centre mids, Selnæs seems to probably have more potential at this stage though Henriksen is now playing a league far more competitive than Norway's own, the Eredivise with AZ Alkmaar)
-Pedro Obiang, Nenad Krstičić and Roberto Soriano (a trio of youngsters - I'm using central midfielder in fairly broad terms capturing all three - all at Sampdoria all of whom have been quite impressive in helping Samp climb back from the poor performances of recent seasons past, Obiang is clearly the best and is thus being montiored around Europe, but there is also wide interest in Soriano and Krstičić)
-Jordy Clasie (the next 'Wesley Sneijder' possibly, he's definitely a fine young Dutch controller pulling the strings for Feyenoord's midfield, Vitesse's Marco van Ginkel is the poor man's Clasie...but given our association with Vitesse he may be an option worth considering also)
-Players who should also be of interest; Leon Goretzka, Lorenzo Crisetig (huge raps on both of these lads, haven't seen enough of them myself to pass final judgement though), Alen Halilovic, Julian Green, Raphael Holzhauser, Paul Pogba (will struggle to free him from Juventus), James Ward-Prowse, Oliver Torres and Federico Viviani.
-Guys who I've previously classified as Defensive Midfielders but are equally potent Box-to-Box chargers, Moussa Sissoko, Etienne Capoue, Arturo Vidal, Kwadwo Asamoah, Claudio Marchisio (I have to say that Juventus have a pretty great midfield at the moment), Fernandinho, Paulinho and Marouane Fellaini.
There's way too many names here to hyperlink them all...but the vast majority are regularly discussed anyway and for players that are less well known, there's always Google.
