Arsenal have struggled for much of this season, but this competition offers them an opportunity to make it a good ending if they can win and qualifying for the Champions League like Manchester United did last season.
The North Londoners have enjoyed some good form recently and they were in total control in their Premier League game against Stoke City at the weekend where they emerged 3-0 victors. The return to Alexandre Lacazette is also a major boost for them ahead of this game especially after he marked his return with a goal for the Gunners.
That win over the Potters makes it 4 wins from the same number of games including their impressive two-legged win over Milan in the Europa League last round, even more impressively they have netted 11 times in those matches, conceding just once. That defensive solidity could help them win this competition.
CSKA Moscow are not one of the biggest teams still in the competition but they are not to be underrated as they showed in the last round against Lyon. They trailed the French side from the first leg 0-1, but they produced a very inspiring performance to win 3-2 at Lyon in the return leg. They are in good form at the moment as they have won 6 of their last 7 games in all competitions.
