Sir Alex Ferguson's insatiable appetite for trophies is the key to his success, according to Arsène Wenger.
The Scot needs just a point against Arsenal on Saturday or Hull City next week to clinch his 11th Premier League title as Manchester United manager. If Ferguson is crowned for the third successive season it will take United level with their old rivals Liverpool on 18 championship wins.
That looked highly unlikely when Ferguson took charge at Old Trafford in November 1986. At the time United trailed Liverpool by 16 titles to seven, but the gap has closed steadily since Ferguson's first Premier League triumph in 1993. Sixteen years on he shows no sign of stopping and Wenger attributes that to Ferguson's incredible drive.
"I believe the hunger never goes, until the last day of your life, the real hunger never goes," said the Frenchman.
"That is nothing to do with the number of trophies you have won or the amount of money you have made. You either want to win in life, or you do not want to win in life. It is as simple as that.
"It is only difficult to accept for people who do not have that drive. People who do have that drive, they understand that the only thing which matters at the end of the day is how much you want to be successful."
United have not had it all their own way this season. Liverpool have threatened throughout the campaign and Chelsea also made a late dash for the title when United faltered in March, but Wenger has been impressed by the champions' response.
"United bounced back very well, and credit to them," he said. "Today, they look the best team in England, and they are.
"That is credit to Ferguson as well, but it also shows that nothing is definite, it can all turn very quickly.
"They have different resources [to us], so you cannot compare the two clubs on that front. But United have bought very well and invested very well."
