Cape Town - Everton manager Roberto Martinez has urged the England setup not to select midfielder Ross Barkley for the U21 European Championship later this year.
Barkley earned a call up to Roy Hodgson's full England squad for the European Qualifier against Lithuania at Wembley on Friday and the friendly with Italy four days later in Turin.
The 21 year old is also eligible to represent England in the U21 European Championship and almost certain to be chosen by Gareth Southgate for the tournament in the Czech Republic in June.
