Arsenal goalkeeper Wojciech Szczesny believes the signing of Alexis Sanchez has sparked a turnaround in the form of Mesut Ozil.
Sanchez joined from Barcelona for £35m ($54m) last summer, helping the club secure an automatic Champions League place and retain the FA Cup.
During the same campaign, Ozil enjoyed a timely return to form having struggled during the back-end of the 2013/14 campaign, scoring four goals and making seven assists in all competitions for Arsenal.
Ozil's performances in both the semi-final and final of the FA Cup against Reading and Aston Villa were particularly impressive as the Germany international rediscovered his very best at the sharp end of Arsenal's season.
And Szczesny believes Sanchez has made all the difference to Ozil, while Theo Walcott's recovery has also played a role.
"His calmness and his vision on the pitch is something that you don't get to see when you watch 90 minutes of football," he told Arsenal's official website.
"Sometimes you're out there training with Mesut and he just comes out with some ridiculous passes.
"I'm back there and see the whole pitch so I should be able to see all the passes but what he does is just different class.
"I really admire Mesut, love watching him and training with him out on the training pitch. With all the players fit, he's had more chances to play with top-quality players.
"Also with the likes of Theo coming back and Alexis signing, he's had more chances to play balls through the defence and cut teams open.
"He's had a chance to play with fantastic players and it obviously makes him better as well."
