David Luiz completed his return to Chelsea on transfer deadline day as the club announced they had re-signed the Brazil defender from Paris St Germain on a three-year deal.

Luiz's switch back to Chelsea, confirmed by the club just after Wednesday's 11pm deadline had passed, reportedly cost them a fee of around £30million, two years on from them selling him to PSG for £50million.

Wednesday also saw the Blues complete a deal understood to be worth £23million for Fiorentina's former Bolton defender Marcos Alonso.

Arsenal midfielder Jack Wilshere made his season-long loan switch from Arsenal to Bournemouth.
