The same goal again and again and again and again

Hard to disagree.

The telling thing is he's mostly played well even disregarding his age, which is what tells you it's a system problem.

I don't even think Caseniro was playing badly. He was trying to over compensate as a playmaker where he had no one in midfield with him, at the same time as having to single handedly pick up both the ball carrier and their 2-3 passing options every single time we got countered.

Mainoo tends to sit a bit deeper which means he doesn't have to worry as much about players running past him, but also we do things like go 4 games without scoring a goal..
 
Without being critical of any particular player. How many of those goals came when Kobe played? Some players have an instinct for their positioning, whereas some leave gaps and fail to see the danger until it’s too late. 100% the midfield we need is Casemiro alongside Kobe with Bruno ahead. The positional sense Cas and Kobe possess is so far ahead of the rest of our players it’s bordering on daft. Once we’re able to field that midfield with Martinez and Varane reunited behind them. Our game will drastically improve. Not once this year have we been able to field our strongest 11 though.
