Not an abundance to choose from of the desired capacity and standard.
As had already been mentioned Etihad complex and FC Utds, possibly Edgely Park.
Not that many other options further a field Bury and Oldham.

Think the Etihad Campus stadium was negotiated last season for an early rnd CC fixture , if we were drawn at home and depending on the opposition .

As for Wales the only plausible is is to convince either Widnes / Warrington to ceed home their advantage in an away fixture in the super 8's at the racecourse ground . if the fixture was a' dead rubber 'it wouldn't happen.
