Louis van Gaal warned Adnan Januzaj that he must improve his all-round game after the Manchester United winger scored the only goal at Aston Villa on Friday in his first start since February.
United manager Van Gaal this week stressed that there is no way Januzaj will be allowed to leave Old Trafford amid reported interest from Sunderland.
Belgium international Januzaj was a surprise inclusion in United's starting line-up for the trip to Villa Park and repaid the faith shown in him by scoring his first Premier League goal since April 2014.
Speaking after the game Januzaj responded to transfer talk by telling Sky Sports: "It was only rumours, I'm happy here and of course I'm going to fight for my place."
"He scored a wonderful goal, but all the other aspects of football you have to show. I'm pleased because with this goal we have won, but there is more than scoring a goal," the former Netherlands coach told Sky Sports.
He added: "There were a lot of unnecessary ball losses [from Januzaj]. Also from Memphis (Depay), a lot of ball losses and that's why there were not a lot of chances."
He added: "The start to the season is better than last year, but that is not so difficult. We had one point at this stage and now we have six, so I am very happy.
"There is still a long way to go. You cannot expect it with only four weeks' preparation. You need more matches to come in the form I think we can show."
