Champions League: Messi joins century club as Barcelona advances

Lionel Messi scored his 99th and 100th goals in the Champions League to send Barcelona through to the quarter-finals for the 11th straight season with a 3-0 win over Chelsea on Wednesday.

Barcelona advanced 4-1 on aggregate following a 1-1 first-leg draw in London.

Messi beat Thibaut Courtois with two strikes between the Chelsea goalkeeper's legs from very tight angles on the side of the box. He struck the opener three minutes into the match and took Barcelona's third goal in the 63rd.

But the most dazzling moment from the Argentina forward, who returned from missing one match for the birth of his third son on Saturday, came when he helped Ousmane Dembele score his first goal for Barcelona after he stole the ball from former Barcelona teammate Cesc Fabregas and darted past two would-be tacklers in the 20th.

Barcelona remained unbeaten in 25 straight Champions League matches at Camp Nou, a run that dates back to 2013. The hosts also stayed in contention for a rare treble of titles. They lead the Spanish league and have reached the final of the Copa del Rey.

Chelsea will now have to focus on finishing in the top four in the Premier League to return to tournament. It is currently in fifth place.

Bayern Munich easily moves on

Bayern Munich easily advanced to the quarter-finals for the seventh straight year with a 3-1 win at Besiktas on Wednesday.

Thiago Alcantara, Gokhan Gonul's own goal and Sandro Wagner gave Bayern an 8-1 win on aggregate following the side's 5-0 victory in the first leg of the last-16 tie.

That result left Besiktas in need of the biggest comeback in the competition's history, and coach Senol Gunes reacted with seven changes to the side that lost in Munich. Only Caner Erkin, Gary Medel, Ricardo Quaresma and Vagner Love kept their places.

Despite the huge advantage, Bayern's Jupp Heynckes sent arguably his strongest side out as the 72-year-old became the first coach to claim 11 consecutive wins in the Champions League.

The team selection paid off as Thomas Mueller crossed for Thiago to kill off any Besiktas hopes of a huge upset in the 18th minute.

Bayern's away goal meant Besiktas needed seven in response to progress. The visitors' level consequently dropped and Besiktas improved toward the end of the half.

Gonul started the second half with an own goal, minutes before a cat on the sideline caused referee Michael Oliver to halt the game briefly. It resumed after the cat jumped back over the advertising hoarding.

Love got the fans cheering again when Gonul pounced on a mistake from David Alaba to set the Brazilian up for Besiktas' consolation goal before the hour-mark.

Alaba atoned by setting up Wagner for Bayern's third in the final minutes.

"We completed the job and now we'll look ahead to the next round," Mueller said.

The only concern for Bayern was an apparent foot injury for Thiago, who was visibly frustrated as he went off in the 35th for James Rodriguez.

"I don't think it's too serious," Heynckes said.

The home fans spent the last 15 minutes celebrating their side, singing and waving their flags in recognition of the team's campaign. Besiktas was playing in the knockout stages for the first time after topping its group ahead of Porto, Monaco and Leipzig.

Bayern fans are hoping for a repeat of Heynckes' treble from his previous stint in 2013. Their side can wrap up the league title this weekend, while a cup semifinal against Schalke also awaits.
