Our last 3 games (FA cup final + 2 games this season), we have to remember we've played 4 midfielders. So it's not surprise we've looked a bit more solid as we've not played with any striker and had an extra midfielder on the pitch, but that's not a long term solution. At some point a striker will have to come back into the team and we'll revert back to 3 midfielders.
It's really a question if we're happy going into the season 50/50 on whether we finish top 4 or we really want to be confident our squad makes us favourites. Between United, Liverpool, Spurs, Newcastle, Chelsea, Villa, you really have 6 teams who could finish anywhere between 3rd and 8th. Competition is fierce.
I mean, watching the Fulham match I wouldn't be particularly happy with the control we had (or lack of) against a lower half team at home.
Casemiro-Mainoo as our first choice double pivot has some qualities between them, but it's also missing some attributes, and to not even have 2 quality alternative players is a major weakness.
