Manchester United striker Danny Welbeck has admitted he found life under David Moyes difficult but refused to confirm whether he is considering his future at the club.
Welbeck has spoken for the first time about comments Moyes made last December saying he needed "to be the last off the training field" and was not following the example being set by some of his United teammates.
Talking to reporters at England's World Cup training base in Portugal, Welbeck has now said: "I was pretty surprised [at the Moyes comments] to be honest. Before he made that statement I was doing extra training. Maybe he just didn't see it.
"I've grown up at Manchester United and been professional all through my career and I always do extra work. It's born and bred in me to do extra work after training and maybe he wasn't seeing that extra stuff. I was doing extras in the gym and on the pitch."
Welbeck also said he had struggled when played out on the left last season, as he believes he is most effective in a central striking position.
"It does get frustrating. You want to be playing in a certain position and you're not getting the opportunity to do that," he said. "It's the same for everyone -- when they are being played out of position, they don't really like it. I'd like to play central. I've been playing on the left for a while and it's got to the time where I want to stake a place up front.
"My goals-per-game ratio is better for England. I'm much more free up front as there are three in midfield and three up front. That way there's a bit more defensive cover rather than me being that defensive cover. Maybe I'm kind of let off the leash a bit more for England than United.
"For United I'm more likely to be left wing of a four-man midfield with only two centre-mids so it's a bit more difficult for me to maybe make those runs to get in and score those goals when I've got to think about my defensive duties as well."
Asked whether he was considering his future at the club, he replied: "I'd rather not answer that question."
However, he was encouraged by the confirmation that Louis van Gaal would take over as United manager for next season.
"I heard the news about Van Gaal and I am happy," Welbeck said. "He is a great man, a great manager. Looking at his CV tells you he has managed at some big clubs. I'm pretty sure he will be watching the World Cup. I want to make sure I show my quality."
