Ninety minutes to overturn a 2-0 lead – the Red Devils used to do it five minutes plus Fergie time.
How times have changed though and last Sunday was a good example as Louis van Gaal's side struggled to score once in 90 minutes to force a home draw against West Ham in the FA Cup.
I can't see the current team overturning a 2-0 first-leg loss at Liverpool that should have been much heavier.
United must score first and fairly early to have a sniff and that's not been their forte – and remember they have a derby at Man City on Sunday.
An away goal kills this tie and Liverpool have the players to profit on the break such as Philippe Coutinho, Roberto Firmino and even Daniel Sturridge if he starts.
Firmino netted in the first leg and has been in great form – he is 11-4 at bet365.
Anthony Martial is back among the goals and after his strike against the Hammers he is 12-5 at Stan James to net.
Elsewhere it's all over for Spurs after their 3-0 defeat in Dortmund so this a game to leave alone.
It could be all over too for Gary Neville if his Valencia side exit at home to Athletic Bilbao. The Basque side won 1-0 at home and 3-0 at the Mestalla in La Liga recently and are 7-4 at bet365 to complete a hat-trick of wins.
Sevilla are going for three titles in a row and should finish off Basel after a 0-0 draw in Switzerland. They are 4-9 at Stan James and likewise Lazio can sink Sparta Prague after an away draw and are 2-5 at Ladbrokes.
Liverpool not to lose
