It depends on whether a clause is put in the deal - in the case of Mancienne there must be as Ancelotti said it was an option. What is really interesting in this case is that Mancienne himself said sometime ago that he rarely speaks to Ancelotti and that his future depends on our scouts rather than Ancelotti, we even tried to sell him to Wolves. Now the club realized their colossal mistake* and may try to bring him back. One could argue that this u-turn has something to do with Arnesen's removal. I, for one, hope that we bring both Mancienne and Matic back. We should have never loaned them out in the first place and using them + Sturridge would have greatly benefited our season. We cannot know if Ancelotti would start either of them but I suspect that Mancienne's 100+ career appearances and EPL experience would have made him more usable than McEachran or Bruma. *Our squad size
