Chelsea and Manchester United are chasing Lyon striker Moussa Dembele for the summer market.

The Mirror says Chelsea are determined to back Frank Lampard in the summer market after the Blues boss publicly voiced his frustration at a lack of signings in January.

Lampard wanted reinforcements to bolster his push for a place in the top four but also knows that he is under pressure to get back into the Champions League.

United are also long-term admirers of Dembele who is regarded as one of France's best young talents and that could spark a battle between the clubs.

Lampard likes Dembele's versatility, likes young players and believes he is a better long-term option than PSG veteran Edinson Cavani and Napoli's Dries Mertens.

Lyon made it clear that Dembele was not for sale in January - but that is expected to change in the summer
