I'm rather confused by the entire bid. You can't really fake a bid, so assuming it's been made you have to think:
1) ESR have actually told us he wouldn't mind jumping ship. You rarely bother making bids for high value targets unless there's some traction to indicate interest on the other side.
2) We are aware Arsenal are tight for money and are considering this to be an opportunity to force them to spend money they don't have on his contract, and thus they will be less of competition for other players.
3) Someone on our end is off.
4) Grealish's injury is a concern and we want extra depth.
I dunno. The entire story seems odd.
What makes it even more odd to me is the size of the bid. £ 25 million is nowt for a young English players of that talent. Especially after blowing £ 35 million on a championship CAM. Realistically even with 2 years left on his contract, you're looking at £ 50 million at the bare minimum. So what's the point of making a public ridiculous offer. I really don't get it.
