The long wait is over – the Champions League is back.

Europe's elite competition resumes on Tuesday with the first two matches of the round of 16, with Basel hosting Manchester City and Tottenham facing Juventus.

Pep Guardiola's City have been in irresistible form in the Premier League and need only six more wins to claim the title, as they pursue an unprecedented quadruple of trophies.

They were arguably dealt a favourable draw against Basel, but the Swiss champions have an impressive record against English teams on home soil and will take heart from Shakhtar Donetsk overcoming City in their final group game.

Juventus, beaten finalists last season, finished runners-up to Barcelona in their group but have gone from strength to strength in domestic competition since the turn of the year.

They put their formidable home record on the line against Tottenham, who finished top of a tough group featuring holders Real Madrid and Borussia Dortmund, and have begun to look like dark horses for this year's trophy.

Here, we look at some of the key Opta stats ahead of Tuesday's encounters...
