To be honest, I don't see us being a Club who can attract a top manager at the moment. The likes of Howe, Silva, Dyche, etc. are about our heavy. So if we can bring in a Manager of Wengers' footballing stature, then we should do it. He does have a winning pedigree and mentality, he could attract players to our Club who otherwise wouldn't give us a second thought, and when he leaves we could be better placed, and a more desirable destination, for Managers other than Howe, Silva, Dyche, etc. to consider.
If we make our next Managerial appointment another "isn't he doing brilliantly with what he's got" media darling, and get it wrong (once again), then we could and up deep in it, and find ourselves struggling to even attract the likes of Neil Warnock in the future.
