Manchester United: Louis van Gaal booed by fans over Anthony Martial substition in CSKA Moscow win

Manchester United striker Anthony Martial was left disappointed with his own performance in his side's 1-0 Champions League victory over CSKA Moscow. Martial, 19, failed to test CSKA goalkeeper Igor Akinfeev, extending his goalless run to four games after his blistering start to life at the club.

The France international was replaced by Marouane Fellaini after 66 minutes, a decision that was met by boos by those in attendance to Old Trafford, who proceeded to chant the attacker's name as he made his way to the substitutes bench.

Despite the negative reaction to Louis van Gaal's decision to withdraw the striker, Martial admits he was having a poor game and has vowed to improve. "Bad match for me tonight but a good win #workhard," he wrote on his Instagram page.

United fans in attendance on Wednesday also chanted "Attack attack attack" and "We want to attack" in response to the clubs recent dreary performances, but Ban Gaal felt the was vindicated in his decision to withdraw Martial and move Rooney upfront.

When asked if he heard the boos when the player was taken off, van Gaal told reporters: "Of course I heard, I am not deaf. This is the opinion of the fans, but afterwards, they shall not be disappointed by the decision of the manager.

"Wayne shall always contribute in a game. I am very happy because I put him again in the striker position and he scored. I am very happy about the result and that we are top of the group."
United enjoyed an impressive start against the Russian champions but were made to wait until the 79th minute for their goal when Rooney headed in Jesse Lingard's fine cross.
