|Chelsea Player Ratings|
|Player||Half-time Rating||Full-time Rating|
Petr Cech: The Chelsea keeper rarely had a thing to do in the first half as his team dominated possession.
Branislav Ivanovic: By his standards, Ivanovic had a fairly quiet first half for the Blues.
Gary Cahill: Cahill only made 33 touches, but they were effective ones as he had a 92 percent pass accuracy. He also had five effective clearances.
John Terry: Terry did have a pass accuracy of 100 percent, but that stat is a bit skewed since he made just 18 passes.
Cesar Azpilicueta: Azpilicueta was very active at left-back as he marched forward in attack on numerous occasions.
Ramires: Earned a free-kick late in the first half after being taken down by Joe Bennett. That free-kick presented Oscar with the opportunity to fire on goal.
Nemanja Matic: The defining moments of his first half came in the 37th minute when he made a commanding tackle on Agbonlahor to deny a Villa counter attack and in the 41st minute when his goal was disallowed due to a handball.
Oscar: The Brazilian did not shine as bright as his teammates in attack as neither of his two attempted crosses found someone else in Chelsea blue. On a positive note, Oscar did have the lone shot on target.
Willian: Was very active at the beginning of the match, but he did pick up a yellow for a hard foul on Karim El Ahmadi.
Eden Hazard: Hazard was the most positive player in the Chelsea attack during the first 45 minutes, but a breakthrough could not be had.
Fernando Torres: Torres did attempt three shots, but none of them were on target.
Cech: There was nothing Cech could do about the skillful strike that Delph scored on in the 82nd minute.
Ivanovic: Did complete 87 percent of his 47 passes, but compared to other games in the past, Ivanovic had a disappointing performance.
Cahill: Was entrenched in a battle with Benteke all day and did a good job of dealing with the towering Villa striker.
Terry: Did not impress as much as Cahill did in the back and he rarely marched forward to become a threat on any Chelsea set pieces.
Azpilicueta: The left-back was brilliant for most of the day, but his defensive expertise could not help Chelsea get past the hosts in the end.
Ramires: The Brazilian made a reckless challenge and was sent off late in stoppage time.
Matic: Found himself in a bit of difficulty in the back after the Blues went down to 10 men, but overall he had a solid game.
Oscar: The Brazilian did not have his best day out on the pitch in 66 minutes of play. He completed just 73 percent of his passes and had a weak shot on goal in the second half.
Willian: Was sent off in the 68th minute for receiving two yellow cards. The midfielder deserved the first one he earned in the first half, but the call for the second yellow was a bit soft.
Hazard: The Belgian made four key passes, but none of them were able to reach the final stage of the attack as Chelsea struggled to get the ball on goal.
Torres: Just like Oscar, Torres did not have his best day out on the Villa Park pitch. The forward made just 38 touches and attempted five shots, but none of them were on goal.
Andre Schurrle: The German replaced Oscar on the pitch, but picked up where he left off as he did not contribute much to the Chelsea cause.
Demba Ba: Ba could not do better than Torres did up front as he was left chasing back to defend as Villa surged forward with the man advantage.
