Heinze is sweating on the result of this week's Premier League inquiry over his wish to join Liverpool.
"We think our case is strong and Gaby definitely has a future here," Ferguson said. "He has another two years left on his contract and nothing that has happened needs prevent him playing for us again. He's still a very popular player in the dressing room and if this thing gets settled in our favour that should be the end of it. I would not be worried about selecting Gaby again. He's a warrior, a fighter. He won't let us down."
