Arsene Wenger believes Alex Oxlade-Chamberlain is his own harshest critic but is confident the out-of-form forward will be included in Roy Hodgson's England squad for this summer's European Championships.
Oxlade-Chamberlain started for Arsenal in their fourth-round FA Cup victory over Burnley on Saturday, but the 22-year-old, whose only goal this season came in the Community Shield victory against Chelsea in August, turned in a below-par display and attracted criticism from the Emirates Stadium crowd.
"I didn't especially feel that, but maybe he misses a goal,'' Wenger said. "I think he is physically there, he worked very hard in training, worked on his fitness and I feel he has the resources to go in one against one.
"He gave an assist on the second goal, but he is harsh with himself.''
Asked if Oxlade-Chamberlain was too harsh on himself, Wenger replied: "Yes, I think so.
"It is not so much a lack of confidence, but he has a high expectation level that he is very demanding of his own performances.
"He is 22, and we forget that these guys are still very young. He is going into the age where he will be really efficient and I think he will make the Euros.''
Oxlade-Chamberlain signed for Arsenal for a £12 million fee from Southampton -- who the Gunners host in the Premier League on Tuesday night -- back in 2011.
But the young star has failed to land a consistent run in the Arsenal team -- either through injury or form -- and has started only seven league games this season.
Wenger, who rejected the notion that the former Saints man was "too nice," added: "He plays many games, if you look at the number of games he has played since the start of the season.
"Automatic choice in our job does not exist any more, especially at the big clubs. You have some players, who they get to that status at 26, 27, but at 22 not many are an automatic choice at the big clubs.''
England manager Hodgson was at the Emirates Stadium on Saturday to see Oxlade-Chamberlain in action, while Calum Chambers, who scored the opening goal of the game, and Kieran Gibbs also made rare starts for the Gunners.
Wenger, however, believes England missed a trick in their failure to snap up 19-year-old forward Alex Iwobi.
Iwobi, who impressed in the victory against Burnley, represented the Three Lions at youth level, but has pledged his international future to Nigeria.
"He plays for Nigeria now, and he should play for England,'' Wenger said of Iwobi, the cousin of former Bolton star Jay-Jay Okocha.
"I think he has shown everybody that he is a good football player again. I find him personally very interesting because his decision making is spot on and his awareness is very interesting.
"I like the timing of the decision making and the quality of his decision making. He always turns when you want him to turn and he plays the ball where you want him to play the ball. It is very interesting.''
