Burnley have a reputation of being tough to beat. Sean Dyche's 4-4-2 is difficult to break down and very well organised, while the strength and size of players in the starting XI means they are always dangerous from set pieces.

Dyche is happy for his players to launch the ball long to strikers running the channels since, as we have seen over several seasons, it works.

It was interesting therefore to hear Unai Emery explain that his Arsenal side had to "adapt the gameplan" at the Emirates on Saturday. Didn't he know what to expect?

How Burnley caught Arsenal by surprise

Burnley, in the past, have sat off the ball and defended in a low block, looking to take advantage of set-piece situations and batter direct passes towards the opposition centre-backs. On Saturday they pushed so high up the pitch that the last man was a often few yards inside the Arsenal half.

"Our pressing was good, it’s hard to dominate here," said Dyche after the game. "Our pressing lines were great."

This aggressive high press caused real problems for an Arsenal side determined to play out from the back. As soon as Bernd Leno played the ball to a centre-back Burnley sprung to action, closing the wide pass, the man on the ball, and the opposite side centre-back.
