The sunday morning Stevie and Carra were on goals on sunday he pretty much gave an answer on this. It was something along the lines of he'd play until he was deemed not good enough for england anymore. Tbh I reckon it depends on the player, some prolong their careers by quitting international football early, others can go until their near 40, just because they have the drive to do it. Gerrard is going to eventually have to re-create himself as a player for us when he loses that burst (i hope he never loses it!!!) but thats going to happen anyway and I dont believe a few more internationals are going to make a difference given the strength and conditioning programs modern day footballers are subjected to. Sure, cut out all the friendlies, that should be an option, but in the past players who have wanted to do both have succeeded. Carra retired because he wasnt getting enough chances to play and went back as an emergency.....had he been a regular starter it could've been a different story for him with internationals! Obviously others will disagree but I do believe its up to the player and his drive to keep going.
