Transfer News: Chelsea Star Will Ask to Leave, Tottenham Set to Make First Major Signing

Chelsea is expecting to receive a formal transfer request from one of its stars from the 2014-15 and 2016-17 title-winning seasons.

The club has seen plenty of comings and going since Antonio Conte arrived, but he has delivered success. Across London, at White Hart Lane, Tottenham is still without a signing but in today's transfer round-up Mauricio Pochettino is on the verge of changing that.

There is also the latest on Manchester City target Kylian Mbappe, as the Monaco forward is still yet to decide his future. Here, Newsweek guides you through all the news and rumors swirling across the Premier League:

Spanish striker Diego Costa will submit a written transfer request to Chelsea, according to The Independent, as the 28-year-old looks to secure his future. Conte told Costa at the end of last season that he would not be in his plans going forward, and the Italian has signed Alvaro Morata as a replacement. But Costa remains a Chelsea player. A return to Atletico Madrid is possible but Chelsea reportedly wants £50 million for the deal.

The Atletico Madrid manager Diego Simeone could also see a transfer deal agreed in the Premier League that would please him but not involve his club. Simeone's son Giovanni Simeone has drawn interest from Tottenham Hotspur and Pochettino is considering making a bid to Genoa for the 22-year-old forward, according to the Daily Mirror.
