The midfielder says he wouldn't be the same player without that aggression in his game.
The midfielder has had an up and down season so far, initially impressing for Swansea City and earning an England call-up before dropping out of the first team picture.
He has since moved on to Newcastle United and impressed once more, putting in several decent displays already since joining in January.
Despite those performances he has often been criticised for sometimes showing an aggressive side to his game that many believe he needs to cut out to truly succeed.
He has refused to do that though, insisting he wouldn’t be the same player without that anger.
“I wouldn’t be the same player if I didn’t have that anger,” he told the Mirror.
“I never want to lose the anger. I think you have to have it to be a footballer. You need it to win.”
“I am not fighting anything, As soon as I go over the white line I want to win. I have been brought up to be a winner. I don’t want to be in second place.”
A look at Shelvey’s career record would suggest that aggression is not actually an issue that has plagued his teams anyway.
In his 130 Premier League appearances so far he has only managed to pick up two red cards, a pretty decent return for a player whose so-called aggression is often criticised.
Given the impact he has had at Newcastle so far as well, there’s no denying that they’d be keen for him to stay the way he is and looks likely to play a big part in their fight against relegation this season.
