Arsenal players were welcomed back to training this week with a series of medicine ball-based exercises as they prepare for a busy pre-season schedule.

New boy Sead Kolasinac was present along with Mesut Ozil and Theo Walcott as the Gunners were put through their paces following a summer away from the sport.

Taking to the club gym the Gunners lined up to take it in turns to throw weighted medicine balls against a target and catch it upon return, working on lower body and core muscles in the process.

Arsene Wenger, fresh off the back of signing a new contract with the Emirates club, watched over the double session as he put his charges to work.

New goalkeeping coach Jens Lehmann was also present and wasted no time in getting straight back into his dominant character around the training field.

In a week's time the Gunners will be heading Down Under for the first stage of their hectic pre-season tour.

'Arsenal is the club which plays the best football in England, so I really wanted to come here,' Lacazette said in an interview with Arsenal Player.

'When I play I like to use my pace and to link up with my team-mates. As a forward of course I like to score goals, but that is not all that I am about.

'I want to give 100 per cent in every match. I want to show I am worthy of the shirt. I want to do everything I can to make sure we win titles,' he added.
