He could have went to Burnley the season before, but didn't, and we then finished 16th. There was a lot of shit after that with the search for a coach. Many fans had started to think we'd be happy to just finish in the top half after what had went on last season, so I imagine he thought he'd take the opportunity to join Ipswich as he thought we wouldn't be in the running for promotion.
There may have been people internally pushing him out of the door too, as it didn't look like he was wanting to rush a new contract, so his value would have dropped dramatically if we hadn't sold him with going into his last year of his contract.
I don't think Ipswich have even tried to get the best out of him tbh, and I'm sure the lad thought he'd have got more games than he's had. It's not been great for him, but I can see why he moved. I just don't see the point in our fans trying to downgrade how good he was for us just because he left.
