I've been very critical of Gareth Southgate thus far but I like the strong message he's sent out with this squad selection. The way Wenger has been hyping up Wilshire yet not playing him himself has been a bit reminiscent of the time when Wallcott got called up in 2006. If he's that great Wenger play him yourself.
Also I like that he's given call ups to the likes of Abraham and Loftus Cheek. It sends a clear to the amount of talent being stacked at clubs like Chelsea, Arsenal, United etc that if you're able to play football regularly you have a much much better chance of playing for your country.
Psychologically this puts a big onus on the likes of Wilshire to break in to that Arsenal first team, and gives an extra incentive for Abraham and Loftus-Cheek to improve.
