But speaking of StarSport, Merson says Sancho – who has 17 goals and 16 assists in the Bundesliga this season – is the Chelsea player to focus on trying to sign it.
“I don’t think Chelsea spending will stop (with Ziyech and Werner),” Merson said.
“Obviously they still want Jadon Sancho, and if they can’t get him they will probably try Kai Havertz.
“One of them will cost almost 100 mł. But this kind of pay transfer for itself. Chelsea could get a good five years from Sancho and still get a big resell.
“You have every chance of getting your money back with a player like Sancho. And if Abramovich starts coming to matches again, they want to be entertained. He would not care to pay £ 100m for a Sancho, if it allows them to play good football.
