There haven't been many English managers at the top clubs, which won't help.
- Man United have never had a permanent English manager in the Premier League.
- Man City haven't had an English manager since the takeover.
- Arsenal haven't had an English manager in the Premier League.
- Liverpool have had 6 months of Roy Hodgson in the last 26 years.
- Chelsea have had Frank Lampard, appointed in a period of huge turmoil, overperformed and then sacked after second season struggles, then Graham Potter who wasn't even given a full season. Chelsea have struggled in general lately.
So of the 5 clubs you'd reasonably expect to win things, there have only been 3 English managers given an opportunity in the 21st century and none were given time.
It's a chicken and egg thing.
And there no English winners because of the lack of opportunity given to English managers at top clubs, or are there no opportunities because English managers haven't won anything?
