Thomas Tuchel: How Chelsea backed manager with Premier League-high £278m summer spend

Chelsea backed Thomas Tuchel with a £278m transfer spend this summer, before sacking him on September 7.

The Blues splashed a record-breaking amount in the summer transfer window on a host of new players - which heaped pressure on Tuchel from the get-go.

Chelsea recorded a league-topping £228.4m net spend, ahead of Manchester United, West Ham and Nottingham Forest.

Additionally, question marks were raised over some of the fees paid on incomings, with Raheem Sterling arguably the only addition to have proven, sustained pedigree in the Premier League. Sterling cost less than prospects Wesley Fofana and Marc Cucurella.
