The Blues were made to play a patient game by Danish title-holders Nordsjaelland before eventually overcoming them for a 4-0 win in Copenhagen thanks to a double from Juan Mata, a brilliant free-kick from David Luiz and a late sealer from Ramires to get their campaign off and running.
United survived an early scare when going down a goal at Romanian club CFR Cluj before Robin van Persie saved the day with two clever finishes both from Wayne Rooney passes for a 2-1 victory whilst Celtic produced a late show to beat Spartak Moscow 3-2 in Russia.
Gary Hooper’s early opener was cancelled out twofold via Spartak’s Emmanuel Emenike before a Dmitriy Kombarov own-goal, after Juan Insaurralde’s sending off, and a 90th minute Georgios Samaras header forced a come-from-behind win for the Scottish champions.
Alexis Sanchez and Cesc Fabregas were amongst the goals as Barcelona defeated Benfica 2-0 in Lisbon but it came at a cost for the Catalan giants with captain Carles Puyol coming from the pitch with a suspected broken arm and a late red card to Sergio Busquets.
