The Europa League quarter-finals conclude on Thursday and Arsenal and Chelsea look well-placed to progress, but the Gunners may have to withstand a Napoli onslaught to do so.
Arsenal hold a 2-0 lead and that could be too big a deficit for hosts Napoli to overcome – but they won’t give up without a fight.
The Gunners have struggled on the road, both domestically and in Europe, having lost at BATE Borisov and Rennes in the knockout stages.
Napoli have been strong at home, with 10 wins and just one defeat in their last 13 games, and they can down Arsenal, even if ultimately they do fall short in their bid for a semi-final spot.
Chelsea managed a 1-0 win in the first leg of their tie with Slavia Prague and will be more comfortable at home, so should be able to win convincingly.
The Blues have won four of their last five at home, with all of those successes by at least two goals, and they can beat a one-goal handicap when they entertain the Czech outfit.
Valencia hold a commanding 3-1 lead in their all-Spanish tie with Villarreal and can claim another win to finish off the Yellow Submarine at the Mestalla.
Villarreal need to score at least three goals and should be able to grab at least one, having scored in each of their last five away games, but Los Che have enough quality to come out on top regardless.
Eintracht Frankfurt were undone by an early red card in their 4-2 first-leg defeat at Benfica, but with two away goals they’re not out of this tie just yet.
The German side saw a nine-game unbeaten run at home ended by Augsburg at the weekend although they probably had one eye on this match.
The hosts can give themselves the best possible chance of progress by beating a one-goal handicap when Benfica visit.
