WATCH: Muller, Coman, Lewandowski Ruthless for Bayern Munich in Rout of 10-Man Besiktas

Watch the highlights of goals and key plays as Bayern Munich routs Besiktas 5-0 in the first leg of their Champions League last-16 series.

Besiktas was one of the most consistent and impressive performers in the Champions League group stage, but its reward was a last-16 date with Bayern Munich, and once it was reduced to 10 men in the opening phase of the first leg, its chances quickly dwindled.

The German powerhouse was ruthless at Allianz Arena after Domagoj Vida's early red card, winning 5-0 and emerging victorious for a 14th straight match in all competitions to all but punch their quarterfinal ticket. Even with 11 men, Besiktas wasn't much of a match for Bayern's powerful attack, but the man disadvantage made it all academic for the Turkish side.

Bayern had an opportunity in the seventh minute, with David Alaba sending in a dangerous cross from the left toward Thomas Muller. The German forward met it deep in the Besiktas box, but he directed his header right of the frame.

Two minutes later, Muller sent in a ball for Robert Lewandowski, but Besiktas goalkeeper Fabri raced off his line to punch the cross away before the Polish star could connect.

Bayern continued to threaten through its forwards, with Kingsley Coman crossing for Muller in the 14th minute, only for him to loft it high of the bar.

Things worsened for Besiktas soon after. Vida was sent off for hauling down Lewandowski after a horrible back pass from Atiba Hutchinson allowed the forward to break through, reducing the visitors to 10 men for the bulk of the day. Nothing came from James Rodriguez's subsequent free kick, but the task became that much tougher with the man disadvantage.

As expected, Bayern continued to dominate possession, and the opportunities followed. Alaba had a great chance from in close deflected, with his volley off the bounce directed wide of the post. Moments later, Fabri made a sensational save on Mats Hummels' bullet header from the doorstep, palming it to safety.

The opener felt like it was coming for Bayern, and surely enough it did a couple of minutes before halftime. Muller got the final touch on it from close range after Coman's cross pinballed to him right in front of Fabri.

Bayern threatened to pad its lead a few minutes into the second half through Lewandowski, who blazed a free kick off the outside of the post, missing Bayern's second by inches.

The second goal came moments later, though. Muller played Lewandowski through on the right channel, and his cutback cross to the center of the box found Coman, who tucked it under Pepe and Fabri to make it 2-0.

Muller made it 3-0 in the 66th minute off a sensational effort from close range. Joshua Kimmich sent in a cross from the right to the near post, and Muller delivered on the volley, turning as he swung his right foot to score his second of the day.

After coming close before, Lewandowski got in on the scoring act, pouncing on a rebound of Hummels's saved shot in the 79th minute to fire home Bayern's fourth in the 79th minute.

Lewandowski removed the shred of remaining doubt in the 88th minute at the far post, meeting Muller's perfect cross to make it 5-0.

Here were the lineups for both teams:
