Arsenal manager Arsene Wenger has admitted that it will be "difficult" for his team to finish inside the top four due to their defeat to Tottenham Hotspur.
The Gunners managed to earn a 2-0 victory at the Emirates earlier in the season, but at Wembley, the North London derby threw up a different result.
Harry Kane was the star as he scored his seventh goal in as many games against Arsenal to give Tottenham a 1-0 win and bragging rights.
If the season ended today, the Gunners would miss out on a Champions League spot for the second year in a row as they sit six points adrift of fourth-placed Liverpool, who have a game in hand.
"The first goal was key and we conceded it," Wenger told reporters after the match. "I have seen the replay and it is no foul, just good centre-forward play. We can only look at ourselves.
"In the first half we missed three or four opportunities on the counter attack which is difficult to swallow, always the final ball. We contained them to very little.
"Once they scored you could see we were wobbling and they could have scored more but in the last 10 minutes we should have come back to 1-1. It will be more difficult to finish in the top four but we have to fight for it. "
Arsenal do not play again in the league until March 1, when they face Manchester City, due to FA Cup action and their EFL Cup final.
