oh and "money to burn" is never as simple as it sounds. Citeh have money to burn, it means they will buy what they can get, waste millions, and offload perfectly good existing players for supposedly better ones. They will find that a lot of players will resist the waft of £££ and go for the big clubs who may not quite offer the same wages, but offer great prospects of silverware.
If Wolfsburg shut the door on a move for Dzeko, or ask too much, then so be it. Same as any other bid for any other player, assess whether the fee asked is OTT and buy or move on
