3 Things that went wrong for Chelsea against Barcelona

#1 Failure to contain Messi

Messi celebrates scoring his second goal

Lionel Messi scored his first goal on his 10th attempt against Chelsea in the first leg. He was in form heading into this clash and found the net immediately after the start of the second leg. Barcelona's tiki-taka passing found a deflection off Marcos Alonso to land the ball in the feet of Luis Suarez, who played it through to Messi.

It was a tight angle for the Argentinian but he found the net following an error committed by Thibaut Courtois, who allowed the ball to go in between his legs.

After scoring, Messi was back in action, forcing Cesc Fabregas to commit an error in the center of the pitch. His run was hard for the defence to track, as he dribbled past them and found an open Ousmane Dembele for the second goal.

The Barca wizard was causing huge amounts of trouble for the entire Blues defence with his pace, dribbling and cutting inside leaving them hard to keep a track of his runs. He scored his second of the night in the 63rd minute, once again nutmegging the Belgian goalkeeper.

The number 10 made an all-around contribution in the attacking half of the pitch, popping up on the left, right and through the middle. He accumulated six dribbles, three shots, six successful take-ons and 38 completed passes along with his one assist and two goals.

100 – Lionel Messi has now scored 100 Champions League goals in just 123 appearances, 14 games fewer than it took Cristiano Ronaldo (137) to reach this milestone. Extraordinary. pic.twitter.com/CfbtoVKb7y
