Robin van Persie knows that tiny margins will decide Arsenal’s success or failure in the “massive six weeks” to come.

The Dutchman helped his side into the Champions League Semi-Final in midweek with a goal in the 3-0 win over Villarreal and victory over Chelsea at Wembley on Saturday would see them reach the FA Cup Final.

But although Arsène Wenger’s side have put themselves in a position to win silverware, Van Persie believes total concentration will be required to complete the job.

“It is a massive six weeks – unbelievable,” he said. “Over the last two and a half months we didn't have massive games - a few occasionally.

“But we have had a massive game against Villarreal now there is a massive game against Chelsea and then Liverpool. We have Manchester United three times in six weeks, Chelsea two or three times, Liverpool once. I can't wish for more.

“But we know the differences will be very small in winning and losing. Look at John Terry in the Champions League Final last season. He was so unlucky to miss the penalty but that meant Man United were the winner.

"When you are in the Final it comes down to little things. It's up to us to come there. We can call ourselves one of the best four teams in Europe and that is about right. Now we want to move on and win it. Definitely.”
