I'm a miserable bastard and I enjoy a good boo, but I don't think I'll boo Tielemans. I don't think I could bring myself to politely applaud him whilst he's playing for fucking Manchester United, but my feelings towards him are closer to what my feelings were towards Benteke, Luiz, Young etc when they left, rather than Yorke, Bosnich, Downing etc.
Which I imagine will be a great relief to him as he signs his £200k a week contract.
