Dig into the data - what will season deliver?

Last season’s head coach Mauricio Pochettino pointed out that Chelsea were the fourth-best side in the Premier League on expected goal difference, a metric which measures how effective teams are at creating chances at one end and limiting them at the other.

The league-high 12 penalties they were awarded certainly helped that. If you exclude spotkicks, they drop to fifth-best below Newcastle. However, the fact it was better than both Aston Villa and Spurs even without penalties suggests there’s something for new boss Enzo Maresca to work with.

However, the Italian has a job on his hands with the defence as 11 teams conceded fewer goals and 13 faced fewer shots last season – a travesty for a club with the defensive legacy of Chelsea.
