Chelsea are targeting Manchester City winger Raheem Sterling as their major summer signing.
The England forward, 27, has attracted interest from major clubs overseas but Chelsea believe they can persuade him to remain in the Premier League.
The Blues would be an obvious attraction for the London-born player, given they are in the Champions League.
Sterling scored 13 goals in 30 Premier League appearances as he won his fourth title last term.
However, he was on the bench for both legs of the Champions League semi-final defeat by Real Madrid and the epic final game of the season against Aston Villa.
