The 62-year-old coach has experience in Champions League ties at the Red Devils' Old Trafford home having being involved in two thrillers with the Red Devils in 2000 & 2003Real Madrid and current Spain boss Vicente del Bosque may hold the key to how los Blancos could ensure qualification for the Champions League quarter-finals on Tuesday.
With Madrid all but out of contention for la Liga, coach Jose Mourinho is under pressure to grab that elusive 10th European Cup success, but first he must overcome the Red Devils in the last 16 in what could be a season-defining moment.
The scenario bears an uncanny resemblance to the situation Del Bosque faced back in 2000 when his Madrid side, who were out of the Liga race, took on the Premier League giants in the quarter-finals and won the second leg at Old Trafford 3-2 to progress to the semi-finals.
"The first time, in the '99-'00 season. It was a game I'll never forget. It was our first year. We had drawn nil-nil at home, and our season depended on it," he told Marca.

"I was really scared of United's strikers: Cole and Yorke. They really opened up the pitch with Beckham and Giggs and I tried to reinforce the central defence with those three centre-backs: Ivan Campo, [Ivan] Helguera and [Aitor] Karanka."
The Furia Roja coach also fondly recalled the impact Ronaldo had at Old Trafford in Madrid's 4-3 defeat in 2003.
"Everyone remembers the three goals by Ronaldo," he added. "What an ability he has to score! The Brazilian was a very positive player, one of those people who are happy just playing football," he said.
