Also read he had an avarage of 1.9 keypasses per match during these seasons.
I just wanted to show his offensively numbers, and they look very good, just by reading them and knowing (also mostly by reading, only seen him play 10 games max) that his offense is much stronger then defense, you could assume Shaw would be more used in big games were we are supposed to defend more and in games against teams with strong wingers and Tellas would be a better choice in games were we are more in control need a extra offensively weapon.
One more thing I've read about him is that he likes to take early crosses which would be great for us when we counter. And not have to wait for Shaw and Rashford to run down to the corner flag and start their Tika-taka passes and hopefully 1 out of 4 goes well and the ball ends up (not fast enough anyway though, usually the opponents defense will be back and organized and ready for the cross, if Shaw or Rashford don't decide to pass it back to Matic then one of the CBs and start over) in the box. With the pace we have in our front 3, Tellas early crosses could easily give us 5-10 extra goals itsef.
4000min = 44.5 matches per season (so you can get an indication about how much he plays every match, based on these informations he seems to be a regular starter and doesn't have to much problem with injuries).
Hope this post makes any sense, standing in a packed bus rushing home to the game (need to visit the store before it starts). LET'S FcKING GO UNITED!
