Do you think we would have had this problem if Poch was still in charge - because I don't. He would have ensured that the players are fit enough to do their jobs, twice a week if necessary.
Puel did not get the team fit and instead gave the players a ready made excuse by saying they couldn't possibly play 2 games a week. The players have been allowed to get lazy - which is the reason we have not seen any real pressing this season.
Puel then proceeded to play a deliberately weakened side game after game. By the time we were out of all competitions, the players couldn't even manage 1 game a week!
The first job of a manager is to get the best out of the team at his disposal and Puel has failed miserably at this and deserves to be sacked as a result.
