Alexis Sanchez has had a superb debut season at Arsenal, netting 24 goals in all competitions, but there is still a side of his game to work on.
The former Barcelona attacker can still add to his goal tally with the upcoming FA Cup Final, in which he is aiming to help the club to retain the trophy.
Arsenal boss Arsene Wenger is insistent that his star man is not perfect, and he is currently on a run of four games without a goal or assist.
The Frenchman attempted to explain why the Chile international is not at his very best, claiming it is the mental part of his game he needs to work on.
He told Arsenal.com: "Sometimes he is too demanding with himself, too quickly upset when it doesn’t go well for him and he has to learn to be a bit more patient and not to be too quickly upset."
Sanchez certainly showed patience in the FA Cup semi-final, when his persistence paid off as he broke the deadlock in extra-time against a dogged Reading side.
Wenger also complimented the 26-year-old, commenting on why he is so admired within the squad.
"He is a guy who has a good combination of talent, combative aspect and fighting spirit. That is why he is liked by everybody here."
The Arsenal boss went onto add that he will be crossing his fingers the forward returns from the Copa America without an injury, with the tournament set to begin next month, and the final being played on July 4.
