Wasn't the problem at the end of his tenure what we have struggled with since? We can't chase matches.
It was a major problem that the club failed to sign Zouma permanently or to sign another central defender with pace. Silva wanted to play with high press and defend with a high line. Things looked OK when ahead in matches, but when behind the team really went for it and threw too many in attack. Leaving Keane and Mina on the midfield line without any form of protection.
First match after Silva was let go Holgate was in the central defense and ended up being voted player of the season by the players. Not necessarily for being brilliant, but he gave some much needed security to the defense with his pace. It is crazy how much better defenders such as Mina, Keane, Coady and Tarkowski play with a quick partner.
It seems like Silva has learned from that period. His Fulham team seems both more patient and balanced.
