Crystal Palace’s swoop for midfielder Adam Wharton from Blackburn looked to be the biggest Premier League move of deadline day as the transfer window closed with a flurry of late loan deals.

The Eagles – fighting to stay clear of being dragged into a relegation battle – are said to have paid an initial fee of £18million, which could potentially see a further £4m in add-ons for the talented 19-year-old.

Wharton, who has signed a five-and-a-half-year contract, feels Crystal Palace is the right place for him to further his ambitions.

“The way they have brought players from the Championship and developed them into world-class players in the Premier League is something that stood out to me,” Wharton said on the club’s website. “It is a big reason why I wanted to come here.”
