I know Vestergaard had a great season just gone but the calibre of forwards is ridiculously different from Championship to PL. He'll be criminally exposed without a world class CB next to him, which we don't and won't have.
Would much rather and happily give Vardy a new deal. Gotta remember it's not just the influence and talent on the pitch that he has. He's probably the most influential off it, too. Having him around even if he's not gonna play every game will be just as valuable.
