I think this is a sensible signing, especially the contract length.
Corberan has obviously learnt from this time last year that we miss Yokoslu more than anyone, we tried bodging it last year and it cost us.
Yok is our best player in my opinion, his only real weakness is his stamina and thats probably stopped him playing higher than he already had, he commands the midfield, M'Vila is a similar type of player and was of similar quality.
Obviously he is older and not played for a while but i would imagine his role will be come on as sub and give Yok a break when possible.
I imagine his sub roles will gradually increase in time length so build up his match fitness that way, if it was a long term deal might be concerned but its short term low risk and not sure you will get many free agents of similar quality to M'Vila who are fully match fit.
I know people shout for the youngsters but although we have some good ones, we dont have any who play the Yokoslu role, if Mowatt or Chabloah get injured we will probably see Whitwell on the bench.
People may say CC doesnt like youth but i disagree, our two highest rated youngsters Taylor and Whitwell have been unlucky as they actually play in positions where we have been really strong this season, Mowatt and Kipre have been bonuses and you would be hard picked to drop any of those two or Bartley and Yok based on form this season.
