The No.22 latched onto Jack Wilshere’s through ball and lifted the ball over Michael Rensing after a few minutes before slotting home Theo Walcott’s cross from close range 10 minutes later.
It was an impressive debut for the forward signed from Lille for £10.5 million this summer, and his manager was impressed.
“He has shown his qualities. He has quick movement behind the defence, the timing of his movement is great and he is easy to find,” Wenger told Arsenal’s official website after the game.
“We have seen what he can bring to the team and he contributes to the high pace we have in the team.
“We played at a good pace in the first half and looked dangerous. Gervinho had a good start and that is always important for his confidence. Overall, I liked today. We took many risks and were exposed to counter-attacks but, overall, I am happy.
“The team is not completely ready but it was the end of our first phase of preparations and it was important to win the game.”
The Frenchman could be forgiven for being distracted during his side’s pre-season campaign as star midfielders Cesc Fabregas and Samir Nasri head for exits to Barcelona and Manchester City respectively. And the latter picked up an injury during the friendly, as well as goalscorer Gervinho and young Conor Henderson.
“
The only sad thing today is the injury to Conor Henderson, it looks quite bad but let us hope that we have good news tomorrow morning,” Wenger added. “He twisted his knee, I don’t know how big the damage is but the first signs don’t look too encouraging.
“Samir got a kick to his ankle, Gervinho got a kick on his knee but both have minor damage.”
