What to look out for?
Messi's new start
Following his arrival in Paris this summer, Lionel Messi can play his first UEFA Champions League game for his new side when they kick off away to Club Brugge. On Tuesday, Cristiano Ronaldo made a record-breaking appearance for Manchester United on his first European appearance for the club since the 2009 final. Ronaldo leads Messi 135-120 in the competition's all-time scorers list.
AC Milan size up Liverpool
Amazingly, Matchday 1 brings only the third competitive meeting for these two giants of European football. The first was Liverpool's shoot-out success in the 2005 UEFA Champions League football: the 'Miracle of Istanbul', in which the Reds hauled back a 3-0 deficit to triumph. Milan fans, though, will remember the last encounter more fondly, the Rossoneri beating the Reds 2-1 in the 2007 decider in Athens.
City begin new mission
Beaten finalists last term, Manchester City will set out with high aims this season, especially as it is ten years since manager Pep Guardiola last won this competition. The English champions brought in Jack Grealish over the summer to sharpen their edge, but Leipzig have fresh talent too – including André Silva, scorer of 28 Bundesliga goals last season.
• Ronaldo can break Iker Casillas' all-time UEFA Champions League appearances record on Matchday 2, when United take on Villarreal: the side that beat the Red Devils in last season's UEFA Europa League final.
• Manchester City eliminated Paris in last season's semi-finals, but they should expect no easy ride at the Parc des Princes on Matchday 2. "It's always special [to face City] because they are one of the best teams in Europe," said Paris boss Mauricio Pochettino.
