He seems to love it in Dundee though. This is his third spell at that club and on Twitter he's wrote that he's there to stay and that he's '#home'. He'd have had to relocate his family here too if he was to sign on as he's just had a child and I'm sure that would have came into play.
If offered the same money between a club he apparently loves and a club he had a decent loan spell at and would have to relocate for I'm sure he'd have still chosen Dundee.
