Well at the moment his demand is low because he’s an ordinary card. When new squad builders are announced it makes certain players more indemand as specific criteria need to be met to complete the SBC. Sometimes that criteria is a squad value over 80 or 83. If its 83 then someone like Mata will be in demand as he has a highish rating.
All of this is under the assumption that the next round of champions league squad builders (in two weeks time) will feature Utd vs Juve as one of the two marque match up SBCs. The reason for this is last time they chose one fixture from Tuesday and one from Wednesday. Our game is the biggest game on that tuesday, plus its Ronaldo and PLUS its United and Juve. Sounds a dead cert to me. This means United players and Juve players will be needed for the SBC. Last time out Liverpool players were selling at 9-10k each, when ordinarily some of them sell at 1k. I’ve stocked up on Mata and Shaw, well as much as i can afford, which isn’t very much as I’m new to this myself. None of this might work out!
