The fullback says his young teammate should feature for England in the tournament after establishing himself as “one of the first names on the team sheet” at Liverpool.
The 19-year-old winger has been in excellent form for the Anfield outfit, netting six league goals this term, and has played a significant role in the club's march to the top of the Premier League table.
“It's all kind of coming together at the right time for him,” the right back told the club's official website. “If he keeps playing the way he is, he's definitely got a chance to be involved in the summer.
“I made my debut around a similar age as Raheem, but obviously I had a few years where I was in and out - so I didn't get as many caps as maybe I should have by now. But hopefully Raheem won't have that gap and I'm sure he'll go on and get more.”
Sterling was used only sparingly at the start of the campaign, starting just once prior to December, but has now established himself as a first-team regular.
“He has been class. When he first burst onto the scene, everyone could see how good he could be,” added Johnson.
“I know he had a couple of months where he wasn't in the team as much as he would have liked, but I think he has bounced back better for that. At the moment, he's probably one of the first names on the team sheet.”
