Manchester United boss Sir Alex Ferguson was delighted with their gutsy win over Wolves.
Park Ji-sung struck the winner two minutes into injury-time, just as it seemed United were about to lose more ground to Chelsea in the title race.
The South Korean's near-post effort gave United their sixth successive win and they head into Wednesday's Manchester derby at Eastlands in confident mood, even if their ranks are somewhat depleted.
"We have done really well to get a result," said Ferguson.
"You have to admire the perseverance of the team because we have done it so many times.
"But it was a long struggle today because we made so many changes."
