Match victor Alonso added: "We definitely deserved it, the first half was 50-50, we start off dominating but then we left a bit of space and they played better at the end". In that 15 minutes, we were not able to do this, so we were in trouble.

That's [regular game time] what I really need now.
"[Sarri] knows me for a long time".
"We could see [against Arsenal] that the fans like me a lot". The players are accustomed to a new broom sweeping clean, but Sarri is also fortunate to have inherited a stronger, better-balanced squad at Chelsea than Emery has found at Arsenal.
