Arsenal manager Arsene Wenger admitted he had never heard of the player whose late equaliser earned Leyton Orient, of League One, a 1-1 draw in the fifth round of the FA Cup on Sunday.

Wenger’s fellow Frenchman Jonathan Tehoue came off the bench to score against the Premier League title contenders. The 89th-minute goal earned Orient a lucrative replay at the Emirates Stadium on March 2, with both teams having discovered before kick-off that the winners will travel to Manchester United in the quarter-finals.

Arsenal will be huge favourites to come through the tie and move on to Old Trafford but the Gunners had no answer to Tehoue after Tomas Rosicky had headed the visitors in front early in the second half.

The Frenchman beat goalkeeper Manuel Almunia with a low drive from just inside the area that Wenger had not been expecting, even though the Arsenal manager is famed for his knowledge of the game.

“I don’t know him. I saw him when he came on but I never heard a thing before,” Wenger admitted.

Wenger does not always lavish praise on the opposition but did so on this occasion.

“That is what football is about,” he said.

“I believed we played the game in the right spirit but you have to give credit as well to Leyton Orient – they never gave up.

“And if you don’t score the second goal then that kind of thing can happen. It is a disappointment, of course, but we are still in the competition.”
