Liverpool meet Chelsea again in an all-English tie while Arsenal face Villarreal and Manchester United take on Porto.

Barcelona meet Bayern Munich in the only tie not featuring an English side.

If United and Arsenal progress, they will meet in the semi-finals, with Barcelona or Bayern Munich awaiting the victors of the Liverpool-Chelsea clash.

Liverpool and Chelsea have met eight times in Europe with four draws and two wins apiece while Arsenal were indebted to a late Juan Roman Riquelme penalty miss when they defeated Villarreal on their way through to their only Champions League final against Barcelona.

United famously lost to Porto over two legs when Jose Mourinho was in charge as the Portuguese side won the tournament.
