As it's been covered repeatedly that the vast majority can't stand him, would be interesting to hear what people think would be a way of turning things around for him and how he could contribute to the team for the rest of the season. Assuming he will stay in the Squad until the summer at least...
I personally think he's a good player that has suffered from losing personnel in the side from last season and being wrongly used by the manager. Of course his performances and attitude have been poor for large spells this season but the manager's must take some blame too. I think the losses of Barkley and Lukaku have really impacted on the whole midfield this season because whatever people think of Barkley, he had the ability to drive forward with pace and both him and Lukaku gave us a threat in the final 3rd.
Last season, we got away with playing Gana and Schneiderlin regularly to good effect, as well as having Davies alongside them. All 3 worked great and I think that's because they were able to play to their strengths and get the ball to more attack minded players. Gana and Schneiderlin are very limited in their creativity and their game relies on winning the ball in the middle and giving it quickly to better players. This season, the only creative player we have in the middle is Rooney and he lacks the pace that Barkley had.
For the rest of the season, Allardyce has to recognise that Gana and Schneiderlin will not work together unless they have someone with pace to pick up the ball ahead of them. In the current squad, Walcott and Vlasic could potentially be that missing link that would compliment Gana and Schneiderlin playing in the same team, but I don't see Allardyce using them in that way. Therefore, he simply has to drop one of them and I think nearly all would agree it should be Gana who starts. So I don't go along with the opinion that Schneiderlin is awful, but like many problems caused by whichever manager we've had this season, he needs to be utilised correctly and what is being tried at the moment is quite clearly not working.
