The agent of Chelsea target Franck Kessie has claimed that the Blues have had a £21million offer for the Atalanta midfielder rejected.

His agent, George Atangana, told Guardian Sport that Chelsea‘s bid of £21m was recently rejected by Atalanta.

He said: “We have a lot of interest from the Premier League – Chelsea, Liverpool, Manchester United, Manchester City and Arsenal.

“I cannot say at this stage how much he will cost but we are talking about one of the best young players in the world.

“But for us the most important thing is that the technical project is the right one for him. Franck is very young so we have to be very careful about his development.

Chelsea are very interested and it is a great club but we must take our time to consider all the options.

“Now we are in January so he has to play at the African Nations Cup for Ivory Coast so I am not going to rush anything.”
