Chelsea are pondering a shock move for Arsenal captain Pierre-Emerick Aubameyang.
ESPN says Chelsea are interested in signing the striker.
The 30-year-old has 12 months left on his current deal and reports yesterday suggested the Gabonese would not be signing a new contract.
That leaves Arsenal with the choice of selling their record signing for a reduced fee or allowing him to run down his contract and leave on a free transfer next summer.
And watching developments closely are Chelsea, where manager Frank Lampard is in the market for a new striker signing.
