Arsene Wenger has backed Danny Welbeck to fulfill his potential, but admitted the striker had suffered during his second serious injury since joining the club.
Having made his comeback last February after a bad knee injury, the 26 year old damaged his meniscus against Man City in April, leading to another significant lay-off.
He made his comeback at Deepdale during the 2-1 win over Preston in the FA Cup, and the Arsenal manager spoke about how difficult it had been for him during that time.
“The patience you need when you have an injury at that age… it’s terrible,” he said.
“To miss the European Championship and on top of he missed the start of the season, but he worked hard.
“You have to go through it and that was a very difficult moment for him. I think he suffered a lot, but I hope, touch wood, he will now have a dream career.”
And on the specifics of being out for that length of time, he said, “When the players are injured they are a little bit out of my sight because I sent him away as well.
“When a player has a long-term injury, sometimes it’s better you get him out and away, that he lives without the players and people who are injured as well.
“Because when he comes in he sees everybody go out there and you have to stay inside… the football club is built for people who are competitive. So sometimes mentally it’s difficult, so we let him go outside and miss this time.
“Of course we spoke with him a lot, but at the end of the day, when something like that happens to you, you deal with it on your own.
“But we try to support him, of course.”
