I think that's unfair on Frank. You say he's not progressive but look what he's build Brentford into, under tight financial constraints too.Moyes / Dyche / Pulis all similar to Frank. I don’t know how he would be progressive at all. Brentford are not a benchmark for continued success. They are a benchmark for stability and low investment = decent returns. I guess that’s what we have become
Are you basically saying that because he's built Brentford into a stable mid table PL team, that's his level and he'll never improve a bigger team.
Take a look at the Brentford forum, they're devastated that he might leave, because they know full well that a huge part of their progression has been down to him.
