I think he wanted others instead of Fellaini, for instance apparently we bid for Khedira, if Fellaini was his number one target then he would have gotten him much earlier. He probably wanted to use Mata as he did Pienaar but when the entire team are under-performing then even players like Mata will look poor. I was just saying he isn't trying to turn us into Everton with the players he is trying to buy, he probably planned on turning us into a much better version of Everton (E.g. Using Mata as Pienaar, Januzaj as Mirallas etc) with some tweaks of course.
I don't think there is anything wrong with being a much better Version of Everton, such a team would be defensively solid and counter attack with full backs ferociously flying down the wing play almost as wing backs, two central midfielders sitting to cover for them and the wide men drifting inside with the view of taking the full backs narrow creating space out wide. Crosses are not a problem either when you have the likes of Baines with a 38% cross accuracy.
He just hasn't executed his plan and unfortunately doesn't seem to be a great tactician nor a great motivator and therefore he should be replaced but he is still a good manager. That said, because his away form is better than Mourinho, Pellegrini and Rodgers, if it is still come the end of the season then I would be content if he isn't sacked (I would rather he is though) providing he employs as his assistant a great tactician so he can focus on actually being a masterful manager as opposed to the jack of all trades. I'm convinced he can get top four next season if he realises how to break down the teams that park the bus and can set up the team to win some of the big games, for this he'll need an expert though. To me, if a top top manager is available, it just makes sense to go for that as opposed to stick with a manager that probably will come good but also might not.
