Though Norwich approach Thursday's Championship playoff semi-final second leg against Leeds with strikers Ashley Barnes and Josh Sargent as injury doubts, manager David Wagner has regrets about allowing Adam Idah to joins Celtic on loan in January.
The 23-year-old has scored seven times in 13 appearances for Celtic with the club closing in on the Scottish Premiership title.
"Every manager likes to have good players, and Adam is a very good player," Wagner is quoted as saying by Pink Un.
"On him, the decision that we made in the winter window to send him out on loan paid off perfectly.
"I was really backing him when he knocked on my door because I thought this was exactly what he needed to go out of this building and this environment where he knows everybody and everybody knows him and to go for a new challenge.
"He has a talent, but sometimes you need this boost, which you only get when you leave a club and go into another environment. The only thing that has got better after Adam left here is the music in the dressing room, because he is no longer in charge of the music box.
"I really wish him all the best for the final at Celtic to finish at a high."
Wagner took over as Norwich manager in January of last year. The German-born former USA international said he and Idah had "conversations more than once" about him leaving on loan.
"I think the idea grew over the last couple of months [before January] and I absolutely have seen where he comes from," said Wagner.
"I had the same thoughts in my head before as well. Then he and we found a very good loan - big credit to Brendan and Celtic for how they've used him. He's made a big impact and hopefully he can help them reach their target."
