Arsene Wenger is concerned that Henrikh Mkhitaryan may have suffered a hit to his confidence after a largely-disappointing stint at Manchester United.
The Armenia international joined the Gunners on Monday in exchange for Alexis Sanchez, ending a see-saw 18-month spell at Old Trafford.
Mkhitaryan was a target for Arsenal before he moved to United in the summer of 2016 but he did not settle into the side and was often left on the sidelines by Jose Mourinho.
Now he has a chance to reinvigorate his stalled career in north London and Wenger has backed the 29-year-old to do so following his challenging time with the Red Devils.
“Yes, of course you worry about how much it has affected him,” he said.
“But as well but it’s a new chance for him, what you want in life is a new chance and I’m sure with his quality that he will take it. I met him at the time (he moved to United), at the time we were close but in the end it didn’t work.”
Wenger insists he can incorporate Mkhitaryan, as well as another potential new recruit in Borussia Dortmund striker Pierre-Emerick Aubameyang, into his squad as players will have to accept they cannot play every week.
“Some people need confidence and to feel security,” he said.
“But in football teams, there is a number (of players in a squad) that pushes you, a number that makes you asleep, and a number that paralyses you.
