The two midfielders are seen to be competing for the same place in Gareth Southgate's team but Mount has suggested that the pair are determined to give their best for the Three Lions.
He said: "There are all different players in this squad who can play in different positions. That is the kind of squad that’s been picked. Players that can be played in higher positions and in deeper positions.
"That’s the focus of the squad. So the comparisons [with Grealish] are not just, I don’t think. Me and Jack do different things, along with all the other attacking players and midfielders. We are focused on our own positions and what we can bring to the team personally.
"Hopefully we can all work together, as I said, over the next three games especially and we can play together and do the best we can."
Mount revealed that he has never seen his competition with Grealish for an England shirt as a "rivalry".
The Chelsea midfielder explained: "I’d never look at it as a rivalry. We are two different players and we do different things, so I’d never look at it as a rivalry.
"We are two team-mates who play for the same country. We want to do the best for each other, for the team and for the country as well.
"We can play in different roles. I look at the way he’s been playing this season, he’s been unbelievable and we both want to bring that to the next three games coming up."
