By Football Italian staff The Diego Costa signing of the year seems inevitable, as the former Barcelona player looks set to remain at the Premier League club.

The former Barcelona striker has made his decision to remain with Chelsea after just three years in England, but he is set to stay for one last season with the Blues.

He will have a two-year deal, meaning the 30-year-old will only be able to leave on loan once.

The deal would only become official if Costa signs a new contract.
