Maybe he's just relaxed knowing that his agent will get him the biggest deal he could only ever dream about. It'll be interesting my to see how the press deal with this once it goes through. I think some will want to slate it but be put back in their box because of the team involved. You can be sure if we'd spent this on the same player the headlines would be pretty damning.
However, the bigger part of this will be the reporting once the season starts. The spotlight will be on this guy every single week, especially when the Stoke away type games come around, and the shitty Europa League games - this bloke will be expected to deliver in those games. Oh, and deliver like Ronaldo or Messi would deliver, not like Gundogan or Silva or even KdB can deliver - £100m+ means goals and assists by the bucket load.
