He's managed to put together a run where he hasn't pulled up since his last bout out. He came to us with a record of 2 previous major injuries and the key question is how long will it be before he breaks down again? He's yet to complete a full 90 minutes at full steam since he came back imo. He still looks short of the pace he showed when he first came. The manager recently said he's not fit enough to start 2 games in a week. Its one for the medical teams but hopefully its not the same people who assessed him when he first signed. A thorough risk assessment on the potential for reoccurring injury has to be done before any consideration can be given to a new contract.
Its a risk/reward dilemma for the new owners. A player who will still be only 25 at the end of his contract, born on April fools day by the way

, who could be a saleable asset if we offer new terms. Balance that against the loss the club has incurred on our record signing and the number of days and games missed. 634 days out and 99 games thats 2 full seasons out of his 5 year contract!
Add in he lost 523 days with Liverpool and 48 games over 4 years not forgetting a bad injury whilst a youngster at Chelsea and the odds on him having an injury free career going forward do not look promising.
He's a popular player no doubt but that alone doesn't warrant a new contract. The club have made a considerable loss on his value as a consequence of his injuries and it would make sense to wait until the end of the season whilst assessing how his body copes, especially his hamstrings, with the demands of playing full tilt 2 games a week.
