Hailing Arteta as a "real midfielder", Wenger gave a glowing review of the player who many had criticised as being an inferior replacement for former Arsenal captain Cesc Fabregas.
But Arteta has repaid the faith shown in his manager with good performances in the past couple of months. This included, most notably, Arsenal's late winner against Manchester City on April 8 when the Spaniard unleashed a fearsome drive that beat City keeper Joe Hart and sealed the win for the Gunners.
Arsenal failed to score past Chelsea at the Emirates on Saturday with the team twice hitting the woodwork in the first half. Arteta could have proved to be the difference as Wenger believes that the midfielder does not give up until the final whistle.
"He has a 90-minute focus on the pitch and what typifies him well is the goal he scored against Manchester City," Wenger wrote in the official matchday programme for the Chelsea game.
"He is a player you don't like to lose because he is an organiser, a winner and has great qualities."
"He first won the ball back through complete focus on what the opponent will do and where he could lose the ball. He then finished the action and scored the goal.
"That is what I call a real midfielder, a guy who is always in the game."
But in the same programme, Arsenal centre-back Thomas Vermaelen opined a reason to keep faith in his team. He pointed out that Arsenal appear to be over their earlier injury crisis and believes that for the remaining three games, the club can be assured of a settled backline.
This should provide some solidity at the back allowing the creative players such as Robin van Persie and Tomas Rosicky to attack without worrying about needing to rush back to help out a patched-up defence.
"It is always positive when you can use the same players at the back and don't have to change too much," wrote Vermaelen.
"I think things have gone well in the last few months. It wasn't good that we conceded twice against QPR and Wigan but there has been an improvement.
"Our players are getting better and growing in experience, we're getting to know each other more and I'm happy with how things are progressing defensively."
Arsenal now get to visit the Britannia stadium to play Stoke next Saturday. Newcastle are three points behind them in fourth place but have played one less game. The Geordies have a poorer goal difference, however, and will need Arsenal to slip up in order to secure third place and achieve automatic qualification to the Champions League group stages next season.
