The Gunners were left frustrated on Sunday afternoon as they dropped two points at the King Power Stadium while producing an uninspiring display.
Many feel Arsenal must invest in a new striker before the transfer window closes on Monday due to the absence of the injured Olivier Giroud until January, but Wenger is adamant he will not be forced into any last-minute panic buys.
“Everybody does that [slip up],” he told Sky Sports. “Manchester City lost yesterday against Stoke and they have strikers. Buying one player doesn’t mean you win the game today. We want to [buy someone] and we are open to it.
“The pressure to buy is always there, whether Olivier Giroud is injured or not. That happens every time you don’t win a game. We have to live with that. We try our best and everybody at the club tries their best to do well.
“We’ve just come out of two very difficult weeks both nervously and physically. Yes we are disappointed not to get the three points, but let’s not put that all down to missing a striker. Football is a bit more complicated than that.”
Wenger did, however, fail to rule out bringing any new faces into the club before the transfer window closes.
“The decision [to add players] isn’t difficult to make,” he said. “It’s finding the personnel that’s the problem. We are open and we work on it, but let’s not fool ourselves that every time the solution to not winning a game is buying a new player.”
Wenger put his side’s disappointing performance at Leicester down to their recent schedule, which has included a two-legged Champions League playoff tie against Besiktas.
“I felt we lacked creativity and sharpness today,” he said. “We’ve had two tough weeks with three away games at Besiktas, Everton and today, and Wednesday the Champions League was very demanding. It’s not an excuse but we were a bit jaded.
“We wanted so much to win the game that we lost any caution and without creating more we were more open to the counter-attack. In the end we could have lost the game.”
