The Gunners are still challenging for honours on three fronts this term as the north London side prepare to welcome Southampton to Emirates Stadium on Tuesday night, with Arsenal currently third in the Premier League table.
Arsenal face a stern test of their Champions League credentials with a last-16 clash against Barcelona later this month.
Wenger’s men also host Hull City in the fifth round of the FA Cup as they bid to win the competition for the third year running.
The Arsenal boss was asked if the Gunners could win all three trophies this season during his news conference on Monday morning, and Wenger refused to rule out the possibility.
Wenger said: “It is [possible] because some clubs have done it. Bayern have done it.
“It is difficult to compete on three fronts. If you ask me is it possible to win on three fronts, it is a little bit different.
“Exceptionally, it can happen. But you need not to have any bad injuries and to have a basis of a team who can repeat performances.
“Maybe to be above everyone else, like Bayern were, like Barcelona were last year. It is difficult. Maybe in Spain even more because they play two legs in the cup.
“Sometimes it is important to give [players] a breather, just to recharge, more mentally than physically. If you play game after game sometimes you are just not fresh enough mentally. Physically you can cope with it.
“I think the team has a good mentality, a good level of humility, and a good togetherness.
“Humility means that you question your performance every time, that you are ready to put a shift in. This team relies a lot on work rate.”
Arsenal are currently three points behind leaders Leicester City as they look to win their first Premier League title since the 2003-04 season.
