PHOTOS: Chambers, Debuchy and Joel Campbell train hard in Austria

Two of Arsenal's summer signings along with a World Cup star hopeful of first-team opportunities were all working hard during a recent training session.

Three Arsenal stars all looking to make an impact for different reasons were working hard during a training session at the club's Bad Waltersdorf base in Austria yesterday, Wednesday.

New recruit Calum Chambers (top) is eager to impress Arsene Wenger in order to begin justifying his £12 million to £16 million price-tag having transferred from Southampton with little first-team game time behind him due to his age - 19.

Mathieu Debuchy (right) must hit the ground running in his debut season as a Gunner as he will immediately replace his compatriot Bacary Sagna, who joined Manchester City on a free transfer earlier in the summer.

Emulating Sagna may not be too arduous a task for the former Newcastle United star as Debuchy convinced France manager Didier Deschamps he was the superior option for the position during the recent World Cup tournament - and he is fully acclimatised to the country and division due to his experience as a Magpie.

Another World Cup player, Joel Campbell (bottom), is beginning to fully ingratiate himself into the red and white camp after excelling on loan at Olympiacos last season and performing commendably for Costa Rica in Brazil.

Chambers, Debuchy and Campbell, along with the rest of the squad, return to North London later in the week ahead of the Emirates Cup competition this weekend.

Arsenal take on Benfica on Saturday before a test against AS Monaco on Sunday. All three will likely feature at various points throughout the weekend.
