I think he has some good qualities and could be an option offering something a bit different.
I do think we'll probably look to sell him again though fwiw.
We knew there was a good chance Sheff Utd could go down so we must be fine with him coming back. Maybe we even saw it like a loan but with the benefit of it helping with FFP. I'd be happy to have him back as the 3rd striking option. More homegrown players for Europe would be useful too.
Be interesting to see whether they end up taking their eye off the ball with Europe. Their form while playing European matches was more patchy earlier in the season.
