Arsene Wenger saw two of his new signings score goals on Tuesday night as Granit Xhaka and Lucas Perez contributed to a 4-0 win over Nottingham Forest in the League Cup third round.
Xhaka, who scored a long-range effort against Hull at the weekend, fired home from a similar distance at the City Ground to give Arsenal the lead in the first half.
However, it was the two goals from Perez, a £17m summer signing from Deportivo, that got Arsenal fans really excited. After all, the Spaniard has been signed to do just that while anything Xhaka does in front of goal is a bonus.
Perez bagged his first goal in an Arsenal shirt on the hour mark after stepping up to dispatch a penalty. Chuba Akpom was clumsily fouled by Michael Mancienne in the box and Perez's short run up and powerful strike to the goalkeeper's right oozed confidence.
He doubled his tally 11 minutes later, chasing down a long pass before hassling the ball from two Forest defenders and rounding the goalkeeper to tap home. It was an excellent goal which drew comparisons with Leicester's Jamie Vardy.
Wenger was rightly pleased to see his new striker get off the mark, saying every goal will add to his confidence, but the Frenchman gave Perez some food for thought as they traveled back down the M1.
The Arsenal boss told reporters: "Of course, a striker is always growing when he scores goals.
"He did well. He's quick, he's determined. He uses well his left foot - a bit too much in my taste. He doesn't use his right enough. Overall he's like all the left-footed players, you know.
"But I like his second goal because he has shown not only technique but determination and fight for the ball and finishing and I like that. The part he played in the goal of [Alex] Oxlade-Chamberlain shows his awareness of other people and it is intelligent play.
"But the most important thing for me is that we win the game. Who scores is not so important but for the player individually it's good because he can convince people he can play for us. It will help himself as well to grow in belief."
Perez now has a good chance of being called upon on Saturday when Arsenal take on Chelsea at the Emirates Stadium. Olivier Giroud has struggled to regain full fitness since the summer and was given Tuesday off to recover from a niggling toe injury. However, if Perez's form continues, Giroud could find his place usurped by the time he returns.
