Theo Walcott in my save hasn't made a single appearance for Arsenal since 2013-2014 season (14 caps 2 goals).
Later on his pace and acceleration have dropped to 16/15. All his other stats are very poor. This is very normal under FM circumstances, but obviously unrealistic of Walcott as he is capable of much more!
For instance;
In FM13 what ever club I sell him to (United, City, etc) he will play 1 or 2 games maximum and then never appear again.
now in FM14, I sold him off to Chelsea (30m pounds !!) in a seperate Arsenal save and he made like 3-4 apperances that season and then never again.
His stats on FM (just pace coupled with very poor long shots, strength, positioning, bravery etc) make him a very poor player for the AI managers.
