The midfielder has endured a frustrating second half of the campaign.
The Everton midfielder endured a disappointing afternoon on Saturday as he failed to have any impact in the 1-1 draw with Watford.
It was a tough game for him, as he was the subject of several tough tackles from the Hornets' defence and midfield.
Tom Cleverley eventually replaced him after he picked up a knock, and Barry says the youngster will have to learn to deal with the extra attention he receives.
“Ross is going to have to deal with that at times,” he told the Liverpool Echo.
“It was pretty clear they [Watford] were going to make it tight in the middle of the pitch and tough for us to get out. It was hard for us to get on the ball.
“For England, you are playing against the best players in Europe, you are not going to have a lot of time on the ball. It is something he will have to deal with.”
Barkley certainly needs to up his game between now and the end of the season, especially if he is to secure a place in England’s squad for Euro 2016.
He has stumbled after a strong start to the campaign, and some are starting to question if that may cost him his place in the squad for France.
With places limited, and Jack Wilshere pushing to make it into the squad as well, Barkley will need to enjoy a strong end to the campaign to ensure he is among the 23 names on Roy Hodgson’s list.
