You can, it's just not very easy.His job is to win trophies. You can't win one every year - even the best managers have trophy less seasons. Let's judge him at the end of the season. It's relatively likely that we'll win a domestic double this year (despite our current form!). If we did you'd have to look back at 4 trophies in a 3 year spell as a very good return from a good manager. On the other hand, if we win nothing this year, 2 trophy less seasons in a row would be poor given our squad. Wait and see what he achives.
I believe minus his year out Pep has.
