The return of Danny Welbeck and Theo Walcott from injuries this past weekend meant Wenger finally has all of his forwards fit and available, and the 67-year-old Frenchman said Monday he has never had so many scoring threats in the same squad.

"I think certainly, number-wise and quality-wise together, we never had so many players who could perform and score goals. Certainly, never," Wenger said ahead of Tuesday's Premier League game against Watford.

That, of course, led to obvious comparisons to the "Invincibles" team featuring the likes of Thierry Henry, Dennis Bergkamp and Robert Pires in attack.

"I had the quality, but [not] the large number," Wenger said of that team. "We had Bergkamp and Henry, and after that Robin Van Persie behind."

Now he has Alexis Sanchez, Olivier Giroud, Walcott, Welbeck and Lucas Perez who can all be considered proper strikers, along with attacking midfielders Mesut Ozil, Alex Iwobi and Alex Oxlade-Chamberlain.

The quartet of Sanchez, Walcott, Giroud and Ozil have combined for 50 goals in all competitions, while Welbeck netted a brace in his first start of the season in Saturday's 5-0 FA Cup win over Southampton. Perez has chipped in with seven goals and six assists despite making just nine starts so far, while Oxlade-Chamberlain has a career-high six goals to go with seven assists for the campaign.

The only question now for Wenger is how does he make use of all the weapons at his disposal?

"That's a good question. I don't know, in fact," Wenger admitted. "I think [you] make the decision for the next game that you think is the right one. Sometimes you consider the problem that you face, sometimes you consider the fitness of the players.

"The fact that, for example, they have played three days before and whether they have recovered or not. You just try to be honest in your decision and keep everybody on board."

That might be Wenger's biggest challenge going into the decisive part of the season -- keeping all his players happy. Because unless the injury problems flare up again, the Frenchman will struggle to even fit all of his forwards on the bench.

The good news is that there will be plenty of games coming up for the Gunners, who are through to the fifth round of the FA Cup and resume their Champions League campaign next month with a difficult tie against Bayern Munich.

"It helps [having so many games]. It's important to stay in all the competitions, because if you have one game every week and you have seven strikers, I wish you good luck keeping them all happy," Wenger said. "It's impossible. And people want you always to buy more. And after, when you have them, they say how do you keep them happy now?"

However, Wenger also said that their packed schedule could be a disadvantage when it comes to chasing Premier League leaders Chelsea, who are eight points ahead of the second-place Gunners ahead of their clash at Stamford Bridge on Saturday. Chelsea and Liverpool are not playing in Europe this season, which Wenger said gives them "a little advantage" in the league.

And he said the six-way fight just for a place in the top four Champions League spots means there is no room for mistakes.

"That's why every game is a final," he said. "That's why the Burnley game for us was a final, and tomorrow again it will be a final. It's so tight."
