The winger, who came off the bench, is now facing growing interest from Arsenal. Reports (via The Mirror) say Chelsea have slapped a £50 million price tag on him. But when Maresca was asked about Madueke’s future, he didn’t name names. Instead, he gave a message meant for every player in blue.

Dortmund improved considerably as a collective following the appointment of Niko Kovač, who adopted a system that reduced the need for a touchline winger of Gittens’ ilk. Width was instead supplied from wing-backs, while speedster Karim Adeyemi performed a more prominent role in Kovač’s attack.

Chelsea look set for a very different pre-season schedule to their Premier League rivals. The Blues have spent the last three weeks playing in the Club World Cup out in the United States with a semi-final clash against Fluminense to be contested in just a few days.
