If he does, then I can understand his enthusiasm as far as Ashford is concerned, but I think he's being extremely optimistic in the cases of both Colwill and Bagan (and I like the latter a lot).
That said, all sorts of players who are Championship standard at best have ended up making appearances in the top flight. Don Cowie, Declan John, Craig Noone, Ben Turner, Greg Cunningham, Kadeem Harris, Nathaniel Mendez-Laing, Callum Paterson, Lee Peltier, Joe Ralls, Danny Ward and Kenneth Zohore all played in the Premier League for City, so I guess anything is possible.
