Wenger pleased by Lucas Perez performance for Arsenal
The Spanish signing netted his first goals for the club, striking twice in the second half of the 4-0 win on Tuesday.
Perez's performance pleased Wenger, particularly his second goal – as he fought off the close attentions of a defender before netting.
"The second goal has technical quality and desire, determination and fighting spirit," Wenger said, via the club's website.
"I liked the second goal for that, I liked as well the goal he made for [Alex] Oxlade-Chamberlain.
"I'm very pleased for him."
Granit Xhaka had opened the scoring at the City Ground with a long-range effort before Perez struck from the penalty spot.
After the Spaniard's second, he set up Oxlade-Chamberlain with a fine pass to seal the result.
Wenger was also full of praise for Oxlade-Chamberlain, saying: "He's in good form at the moment, physically.
"It's the first time in a long period that he has been ready to compete and he had a little bit of a slow start in this game but became stronger and stronger.
"I was very pleased for him with the way he finished the game."
