Manchester United midfielder Nemanja Matic called on his team to "do more" after they came from behind to beat Crystal Palace.
After falling 2-0 behind at Selhurst Park on Monday, United rallied as goals from Chris Smalling, Romelu Lukaku and Matic sealed a comeback win.
Matic, who scored the stunning winner from 30 yards in the 91st minute, hailed his team's fightback, but said improvement was needed.
"I'm happy I've scored my first goal for Manchester United," he said. "I know it's not my job but I'm glad it got us the three points."
"After the second goal it was very difficult for us to come back; we showed character and did exactly what the manager wanted us to do," the Serbian said.
"In these kind of games, if we can manage to win we can compete for the title.
"The quality is there but we have to be honest: we need to do more."
Andros Townsend and Patrick van Aanholt had put relegation-threatened Palace in control before United came from behind, and while Matic's goal was his first for the club, Jose Mourinho was not shocked that he stepped up in a big spot.
“He scored with Chelsea an amazing goal like this one at Goodison Park [against Everton],” Mourinho said. “He scored a winning goal in Lisbon in the Champions League against Sporting. He’s scored a few goals – not many – but he’s scored a few goals.
“This season against Benfica, it was half a goal for him and half a goal for the Benfica goalkeeper [Mile Svilar]. But it is a goal of two extra points.”
Mourinho will be hoping for even more from the midfielder as his club heads into a crucial run of the season, with Liverpool next up in the Premier League on Saturday and the second leg of their Champions League last 16 tie with Sevilla on March 13.
