Strauss felt that Pietersen's issue was bigger than the controversial texts sent to South African players.
"A lot has happened over the last seven days. The England cricket team has been in the news for the wrong reasons," said Strauss.
Talking about Pietersen's issue, Strauss said it takes time to heal as it deals with trust and mutual respect.
"We all want to move forward but there are some ongoing issues regarding trust and mutual respect that don't get dealt with overnight and it's going to take quite a long time to overcome those.
While he also added that such issues should not be publicised as they need to be dealt in a different manner.
"My personal point of view is I prefer those issues to be dealt with in private, away from the media without the help of PR companies and press releases," Strauss was quoted as saying by Sportal.
Strauss further added saying that the issue is not pertaining to him and Pietersen alone, while it has become bigger than the text controversy.
"Who knows what's going to happen in the future? It's a bit of a process that we all have to go through.
"It's a broader issue than just the text messages. It's not between me and him, particularly. The text messages sound like I was involved in it but it's a broader issue," he added.
"It's about the team and Kevin and how we interact with each other. I spoke to him over the course of the last week over a number of issues," Strauss explained.
Meanwhile Kevin Pietersen having apologized for sending provocative texts to South African players about Andy Flower, Andrew Strauss and on the atmosphere at the dressing room, is hopeful of returning to the national T20 side as ICC has set Saturday as a deadline for announcing the final squads for T20 World Cup.
