Arsenal stars return to training as Alexandre Lacazette arrives at London Colney for a medical

Arsenal have returned to London Colney for the first day of pre-season training

Kolasinac arrived at Arsenal on a free transfer from Schalke earlier in the summer, with the Bosnian left-back already looking a powerful addition to Arsene Wenger’s squad.

Alexis Sanchez was absent due to his exertions at the Confederations Cup but a number of first team stars were back in action, with Mesut Ozil, Danny Welbeck and Theo Walcott all reporting for duty.

Transfer target Alexandre Lacazette was also present at London Colney as the French striker underwent a medical, with the Gunners expected to pay a club-record £52million fee to secure his signature.

Arsene Wenger was all smiles on the training pitch as he oversaw the first pre-season session, and you can imagine his grin will be even broader once a deal for Lacazette is confirmed.
