ARSENAL, MUNICH, BARCELONA GRAB WINS

Alexis Sanchez was involved in all three goals as Arsenal kept their hopes of Champions League progression alive with a comfortable 3-0 victory over Dinamo Zagreb at Emirates Stadium on Tuesday night.

Having provided the assist for Mesut Ozil to open the scoring after 29 minutes, Sanchez found the net either side of half-time to wrap up a vital win for the Gunners.

With just one Group F win to their name prior to Tuesday's tie, Arsene Wenger's side needed three points on their home turf to stand any chance of reaching the last 16.

After dominating possession without threatening early on, they eventually opened the scoring when Ozil capped a well-worked attacking move, netting from the side's first shot on target of the game.

Sanchez doubled the advantage 12 minutes from the interval, before rounding goalkeeper Eduardo to complete the scoring in the 69th minute.

The result leaves Arsenal needing a two-goal victory at second-placed Olympiacos - who were thumped 4-0 at Bayern Munich while the Gunners were blitzing Dinamo - to guarantee progression in a fortnight.

Bayern Munich secured top spot in Group F of the Champions League in emphatic fashion on Tuesday, recording a 4-0 victory over nearest rivals Olympiacos, despite the dismissal of Holger Badstuber.

First-half goals from Douglas Costa, Robert Lewandowski and Thomas Muller meant Pep Guardiola's side had the three points wrapped up inside the first 20 minutes at the Allianz Arena.

The hosts were forced to play the majority of the second half with only 10 men, as Badstuber was sent off after bringing down Olympiacos forward Brown Ideye when he was through on goal.

Yet despite the numerical disadvantage, Bayern added a fourth goal through Kingsley Coman, taking their tally in this season's competition to 17 goals in five matches.

Despite the heavy defeat, Olympiacos still control their own destiny in the battle to reach the knockout stages.

They host Arsenal in the final round of fixtures knowing a draw will be enough to see them advance to the last 16.

Lionel Messi scored twice on his return to the Barcelona starting XI as the European champions cruised to a crushing 6-1 victory over Roma and secured top spot in Group E.

Luis Suarez opened the scoring after 15 minutes of the match at Camp Nou on Tuesday and Messi struck three minutes later to put the hosts in complete control.

The game was over as a contest just before half-time when Suarez scored a stunning volley, before Messi, Gerard Pique and Adriano added gloss to the scoreline in the second half.

BATE Borisov's draw with Bayer Leverkusen earlier in the day meant Barca were already sure of a place in the last 16, but their victory means they have wrapped up top spot ahead of their final game against the Bundesliga side.

Despite only having five points from as many games after a harrowing 90 minutes which also saw Edin Dzeko miss a late penalty before then netting a consolation, Roma are still in pole position to qualify in second place.

The Italians now have to better Leverkusen's result against Barca when they play BATE to reach the knockout stage.
