Reiss Nelson admits Arsenal were surprised with Leeds' high-press in the opening stages of their FA Cup third-round clash on Monday.

Marcelo Bielsa's dominated the first-half thanks to their ferocious pressure and tenacity.

But the Gunners wrestled back control after the break, with Nelson's 55th goal proving the difference.

Speaking after the game, Nelson said: "The emotions are high. They played well in the first half. Leeds are a great team and they pressed us, we didn't expect it. We got the goal in the end and that is the most important thing.

"This will give us confidence to go forward. We want to go to the Palace game and do well."
