Welbeck landed awkwardly after leaping in the air to meet a cross just after the half hour mark against Sporting, and needed oxygen before being stretchered off the pitch.
Iwobi, however, expressed sadness over Welbeck’s injury and wished him swift recovery.
”It’s very challenging mentally, but sometimes it comes in the game and there’s been a lot of injuries, and unfortunately for Danny he’s had a few so we’re going to wish him the best,” Iwobi told Arsenal’s official website.
”Both sets of teams were mentally challenged and we were able to continue with the game, but like I said, we wish him all the best and we will keep on encouraging and motivating him to get back. ”
Arsenal will now tackle Wolves on Sunday in the Premier League fixture at Emirates.
