Arsenal have hit form in recent weeks with eight wins in their last ten outings, and captain Robin Van Persie wants the players to maintain their momentum when they host West Brom in the Barclays Premier League on Saturday.
In the corresponding fixture last year, the Baggies upset the odds after racing into a 3-0 lead at the Emirates Stadium, and could even afford the luxury of missing a penalty before finishing the game deserved 3-2 winners.
Van Persie admits that the Gunners 'switched off' in that game last season, and says that the players cannot afford to do that again this time round.
"We lost to West Brom here last season and we must admit that we switched off that day," the Dutchman told the Official Arsenal Matchday Programme.
"We can not accept that though, so we must not allow it to happen this time. We must learn big-time from that experience.
"There's not one team in this league that you can underestimate. All of them have earned their stripes to be here, and this is the best league in Europe."
After drawing in their midweek UEFA Champions League clash with Marseille, Van Persie emphasised the importance of getting back to winning ways as soon as possible, and revealed how the players are fully focused on getting the three points.
"There is no excuse whatsoever to go into this game with any different feeling," he added. "Especially after what happened last year.
"They were 3-0 up and had missed a penalty - at Emirates that is just not acceptable - so we have to learn from that. So this game is a big one - we have to put something right from last year, and we also have to keep our run going."
