Chelsea are ahead of Arsenal in the battle to sign AS Roma defender Kostas Manolas.

The Mirror says the Greece international has grown into one of Europe's leading centre backs since joining the Serie A club from Olympiakos four years ago.

And Chelsea are ready to activate his £34million release clause, according to reports in Italy.

Incoming boss Maurizio Sarri is believed to be an admirer of Manolas from his time in charge of Napoli.

And that is likely to see Manolas edge closer to Stamford Bridge than the Emirates.

New Gunners boss Unai Emery also needs to strengthen his defence with Laurent Koscielny injured.
