The 26-year-old started every Premier League fixture for Manchester City in the last three seasons but was dropped by Manuel Pellegrini for Costel Pantilimon following a number of high-profile errors.
The Stoke City youngster, however, is certain that the snub will make Hart stronger and insists that he does not want to see Roy Hodgson's N.1 do badly despite any failures potentially opening up doors for a senior place.
"I know Joe very well," Butland told reporters. "We speak every now and again but I gave him space for the last couple of weeks [because] the last thing he wants is people telling him things he already knows.

"I'm sure this short stint out of the team will make him even stronger. He will come back even better than he ever has done before in the World Cup year.
"I don't want to see him do badly. I sympathise with him because I've made mistakes and know how it feels.
"I want to succeed on my own merit but sometimes those opportunities come around because of situations like this. I don't know what it feels like to be in his position right now and that's where I want to get to."
Butland is on loan at Barnsley from Stoke and has made seven appearances for the Championship side.
