UEFA.com's Matchday Live will, again this week, have all the best coverage from the UEFA Champions League as the first four quarter-finalists are decided.
Starting at 19.30CET on Tuesday we will carry updates from FC Shakhtar Donetsk's round of 16 second-leg trip to 1997 winners Borussia Dortmund. We will also have full commentary of Cristiano Ronaldo's return to Manchester United FC with Real Madrid CF, the Portuguese forward's first-leg header having earned a 1-1 draw.
The game between United and Madrid pits together two of football's greatest coaches – Sir Alex Ferguson and José Mourinho – with two UEFA Champions League titles apiece. That is why, ahead of this week's meeting, we want to know your thoughts on who is the best manager in the history of the European Cup?
Josep Guardiola will assume the reins at FC Bayern München this summer and, after a trophy-laden time at the FC Barcelona helm, would no doubt make the shortlist for many. Like the Spaniard, Ottmar Hitzfeld, Brian Clough and Vicente del Bosque are among the coaching luminaries to have won the competition twice. Bob Paisley is the only man to have gone one better, lifting the European Champion Clubs' Cup three times with Liverpool FC from 1977–81.
Carlo Ancelotti is also one shy of Paisley's record, having landed the trophy twice when in charge of AC Milan. On Wednesday, from 19.30CET, we will bring you full commentary of Ancelotti's Paris Saint-Germain FC against Valencia CF. PSG return to the French capital with a 2-1 advantage.
Celtic FC, meanwhile, trail 3-0 prior to their visit to face Juventus in Turin. Though their hopes are slim, Celtic can draw inspiration from the record books. SV Werder Bremen, for example, were 3-0 down against RSC Anderlecht in the 1993/94 group stage with just 25 minutes to play. The Bundesliga team scored five times before the final whistle to complete an astounding turnaround.
Perhaps AS Monaco FC's remarkable fightback against Madrid in the 2003/04 quarter-finals sticks in the memory. There was also, of course, United's last-gasp triumph over Bayern in the 1999 final and Liverpool's astonishing result against Milan in the 2005 showpiece.
Also on this week's show we have interviews with United midfielder Michael Carrick, Valencia forward Nelson Valdez and Shakhtar goalkeeper Andriy Pyatov. We also hear from the legendary Franz Beckenbauer after he received the UEFA President's Award last week.
Do not forget to tweet guest Andy Brassell and me with your suggestions for the greatest coaches and comebacks in the European Cup. You can follow us @championsleague and get your thoughts across using #matchdaylive. The show begins at 19.30CET on Tuesday and Wednesday.
