What the hell has happened to him?

When he first joined he looked exactly like the midfielder we needed, crunching tackles, fast, busy, never giving possession away, in his first 5 or 6 games I thought he could play premier league football. Now he would struggle with non league, one pass tonight straight out to touch was ridiculous and he seems so far off the pace.

I know players have dips and lose form but he’s really gone from one extreme to another in a short space of time and it’s quite startling, there must be a reason behind it?
