Rooney, 26, suffered a horrendous gash to his leg in a tackle after coming on as a substitute in a game against Fulham  a fortnight ago.
The England international star was ruled out of action for around a month and, although there were reports suggesting he could be out longer, he believes his recovery is on track.
"The injury is going well. It could have been a lot worse than what it was. It is up to the doctor. When he declares me fit I will be ready. Overall, I think at the most I will miss four games," the Telegraph quoted Rooney, as saying.
"It feels good at the minute. The timescale put on it was four weeks. If that is the time they feel I need for the wound to heal properly then that is what I will do," he added.
Rooney claimed that his gruesome-looking injury, which was caused after being caught by Hugo Rodallega's boot, was not painful at the time.
"It didn't hurt me at all. I got up ready to play on. I was holding my leg up to the referee to say I needed a physio or doctor on," he said.
"What I don't want to happen is to come back too early when it is not quite healed and it opens up again first game. That would just set me back again another four weeks," he added. (ANI )
