No, no no no no no !!!!!! What you SHOULD be saying is "he would keep them up !" That's what we want to hear.
Chris Coleman is thee greatestest, bestistist manager that has ever lived, or ever will live. Go get him Sunderland, you shouldn't even think about slumming it by appointing the massively overrated Paul Heckingbottom!
Chris Coleman is like Blackpool rock..... he truly has got Sunderland in red and white running right through him. It's in his blood, he was meant to be, he's the man, you know it makes sense.
I think Coleman is a great manager - much more experienced both in the Premiership and at internation level than a guy who is only in his second season of management and never managed above championship level. Coleman also used to dealing with Internationals some of them world class and some not quite so talented He would be able to fit right in to a big club like Sunderland and deal with their more experienced players.
