Champions League - Tuesday 1st November (Matchday 4) round-up.

Both Arsenal and Chelsea, opposition at the weekend, must await progression from their respective Groups as both provided lacklustre draws on an evening where the holders Barcelona and AC Milan became the first sides to advance to the knockout stage of the competition.

Arsenal, who could have qualified with a win over Marseille at the Emirates made three changes to the side that thumped Chelsea 5-3 on Saturday lunch-time with Carl Jenkinson coming in for Johan Djourou, Vermaelen replacing Koscielny and, hat-trick hero at the weekend, Robin Van Persie rested with Park Chu-Young starting his first Champions League game for the Gunners.

The game ended up being a tight affair with little chances for either side and Marseille were visibly delighted with the draw at the final whistle that keeps them in second place in Group F with 7 points, 1 behind Arsenal in first. Van Persie had the best chance of the game after coming on in the 60th minute for the Korean Young but failed to beat Mandanda in the Marseille goal after being excellently put clear by Thomas Rosicky's pass. Van Persie attempted to chip Mandanda into the far corner on his left-foot, only to lob the ball straight into Mandanda's grateful hands.

Borussia Dortmund are third in Group F on four points after beating Olympiakos 1-0 thanks to Kevin Grosskreutz's goal after seven minutes. Grosskreutz's fine strike gives Dortmund their first win in this year's competition and keeps alive Dortmund's hopes of qualifying for the round of last 16. Olympiakos remain bottom of the group with 3 points from their opening 4 matches.

Chelsea headed to Genk hoping to bounce back from the humiliating defeat to their London rivals at Stamford Bridge on Sunday but had to settle for a 1-1 draw after the Belgian side came from 1-nil down and register only their second point of this year's campaign. Andre Villas-Boas again rested John Terry in Europe, favouring Brazilian David Luiz in the centre of defence, one of five changes to the side following the defeat to Arsenal. Juan Mata, Frank Lampard, Daniel Sturridge and Jon Obi Mikel were the men to make way with Raul Mereiles, Oriol Romeu, Florent Malouda and Nicolas Anelka their replacements.

After comfortably beating Genk 5-0 at home last time out, Chelsea were expected to put their disastrous performance against Arsenal behind them but their season's inconsistency continued. Ramires gave Chelsea the lead after 25 minutes, firing past Laszlo Koteles, from an angle, in the Genk goal. Chelsea then took control of the game and were given a golden chance to make it 2-0 when Thomas Buffel handled Flourent Malouda's cross in the Genk penalty area. David Luiz stepped up in the absence of Lampard but his obvious penalty was saved comfortably by the diving Koteles.

Genk came out firing in the second half and deservedly levelled on the hour as Jelle Vossen swept Fabien Camus' cut-back from the left past Cech. Chelsea had their chances to win the game during the remaining half hour of the fixture but couldn't get the win needed for qualification. Chelsea will now qualify if they beat Bayer Leverkusen on Matchday 5 at the BayArena. Genk remain bottom of Group E with just 2 points.

Valencia brushed aside second placed Leverkusen at the Mestalla in Group E's other game of the evening, winning 3-1 and closing the gap to one point between themselves in third and Leverkusen who have 6 points so far, 2 behind Chelsea at the summit. Jonas opened the scoring for the home side with the second fastest goal of the Champions League's history, capitalising on Bernd Lenko's poor clearance to slot passed the Leverkusen 'keeper after 10.6 seconds. Leverkusen managed to equalise before half-time through Stefan Keissling but goals from Valencia captain Roberto Soldado and defender Adil Rami secured the victory for Valencia.

Lionel Messi's 14th hat-trick of his career ensured that Barcelona strolled past 10-man FC Viktoria Plzen thanks to a 4-0 win that ensured the holders' qualification to the knockout phase. Messi's first came from the penalty spot and was his 200th goal for Barcelona in just 286 appearances. Messi is only the second person to score as many goals for the Catalan club and is now just 33 goals behind Cesar Rodriguez, the Spanish striker, who represented the club between 1939 and 1955. Messi was the man brought down in the box after 24 minutes, felled by Marian Cisovsky who was sent-off as a result. Messi doubled the lead on the brink of half-time, with Cesc Fabregas scoring his first Champions League goal for the club after 70 minutes to make it 3-0 and Messi completing the scoring in the 92nd minute to give him his fifth goal in the Champions League this season.

Barca have 10 points thus far, 2 ahead of AC Milan who qualified with a 1-1 draw in Minsk against BATE Borisov, despite taking the lead through Zlatan Ibrahimovic. Renan Bressan scored the equaliser from the penalty spot to leave them 1 point ahead of Plzen as both battle out a Europa League spot in third.

APOEL provided the biggest shock of the night by beating FC Porto in Nicosia to extend their fine run in Group G which sees them sit top of the group by a single point. Ailton gave the Cypriots the lead from the penalty spot just before half-time but the win looked unlikely once Hulk had levelled after 89 minutes with a penalty of Porto's own. Gustavo Manduca grabbed the winner, however, just a minute later and on the brink of the final whistle as he slotted home Constantinos Charalambides' (it just rolls off the tongue) cross. APOEL are now just one victory away from becoming the first Cypriot side to qualify for the last 16.

Next up for APOEL is second placed Zenit St Petersburg who managed to overcome bottom side Shaktar Donetsk. Zenit overcame the Romanian side by a goal to nil with Nicolas Lombaerts' 45th minute header giving the Russians the win. Zenit lie second with 7 points, one behind APOEL, with Porto third with 4 and Shaktar bottom with just 2 points.
