UCL draw: Past encounters with our five possible play-off opponents

Roma, who are not among the seeds, could be paired with Manchester City, Porto, Villarreal, Ajax or Borussia Monchengladbach.

The Giallorossi last faced off against Manchester City in the 2014-15 Champions League group stage. The first match at Etihad Stadium ended 1-1, Sergio Aguero giving the Citizens an early lead from the spot before Francesco Totti levelled the scores with a delightful finish.

In the reverse fixture at the Olimpico, goals by Samir Nasri and Pablo Zabaleta secured a 2-0 win for City, who thus advanced to the last 16 at the Giallorossi's expense.

We need to go back a quarter of a century to find the last match-up with Porto. The two sides were drawn together in the last 16 of the 1981-82 Cup Winners' Cup, with the Portuguese side triumphing 2-0 at home before the return leg in Rome ended 0-0.

Roma crossed paths with Villarreal in the 2003-04 UEFA Cup, also at the last-16 stage. After losing the first leg at the Madrigal 2-0, Fabio Capello's team levelled up the tie on aggregate at the Olimpico thanks to Emerson and Antonio Cassano, only for Sonny Anderson to snatch the decisive goal and send the Spaniards through.

The Giallorossi most recently met Ajax in the second group stage of the 2002-03 Champions League. The Dutch outfit won 2-1 at Amsterdam ArenaA while the match in Rome finished 1-1: Andy van Der Meyde scored in the first minute before Antonio Cassano equalised. The point was not enough for Roma to progress to the quarter-finals, however.

Roma have never faced Borussia Monchengladbach in competitive fixtures before.
