Arsene Wenger says Alexis has rediscovered his “electric” form.
The Chile international has had a hand in seven goals in his last six Premier League game, scoring four times and claiming three assists.
Alexis scored a well-taken goal against Crystal Palace and Wenger says his confidence is coming back.
“He is much sharper,” the manager told Arsenal Player. “He is much more electric in his dribbling and much more confident. He scores goals again.
“He looks to me to be more comfortable in his movement, especially in his movement in behind.
“When he plays on the left, he likes to drift in then come back. When he plays on the right, his runs in behind are better.”
While Wenger was pleased with Alexis’ performance, he was left frustrated by his side’s lack of sharpness in front of goal.
“It was very difficult because [the equaliser] happened late in the game,” he said. "We had so much possession and never really looked in danger. It was a game we absolutely had to win.
“In the end, it was not one of those days where we were free flowing but had to do our job and hoped to get through it. We did the job, but unfortunately we did not get the three points.”
