Since Morgan joined you,

It is mainly a coincidence.
In the 9 games they have played since his arrival in the PL he has started 6. They only won half of those, losing 1 and drawing 2. In the other 3 they won 4-0, 1-0, 4-0 - including that result versus Man City.

As well as Schneiderlin, Davies has stepped up to the first team and done well. Barkley has found form. Lukaku has 9 in 6, Miralles is actually performing now and again, and the defence has become pretty solid at times (although, again, with Schneiderlin they did let in 3 against Bournemouth and Spurs!)

I think we can conclude Schneiderlin is not the reason for the upturn in form - although he has played a positive part of this along with others.

Long term I think he will be a big success alongside Gueye and Davies. Finally being able to pension Barry off will be a bonus for the Toffees.

Schneiderlin has been brilliant,he'll be a big miss if he's injured for the derby.

You are getting Rooney shortly

I will reserve my judgement until he has played to the end of the season.

He arrived unfit and appears to be getting better each game. Gana helps him by using his energy.
