Arsenal boss Arsene Wenger admits he fears Chelsea's mega spending plans this summer.
While the Frenchman has £70million to spend on transfer fees and wages, that will be chickenfeed compared to the cash available for Chelsea's new manager.
It looks increasingly likely Jose Mourinho will be back at the Bridge and sign Atletico Madrid's Radamel Falcao for £53million.
Wenger said: "I'm afraid of what Chelsea can do in the summer.
"We have to be prepared for them to be one of the biggest movers in terms of investment once the transfer window opens.
"They have a great base to their squad, notably young players Oscar, Juan Mata, Ramires and Eden Hazard, but I think they will be busy."
