Chelsea and Manchester City are thought to be leading the chase to sign Bayern Munich winger Arjen Robben.
The Bundesliga club are worried that the 28-year-old, who has one year left on his current contract, could leave for England at a cut price over the summer.
Munich president Karl-Heinz Rummenigge has reportedly offered the Dutchman a club record-breaking £170,000-per-week deal to stay at the Allianz Arena, according to The Mirror.
Robben left Chelsea in 2007 after three years at Stamford Bridge.
