Sigurdsson is confident ahead of the clash against the Gunners as Everton come into the game off the back of two straight wins.
"Confidence makes a big difference," Sigurdsson said.
“It's so important in this league as back-to-back wins gives you momentum.
“Arsenal are on a very good run. They are going for the top four so every game for them is crucial but if we can build on the last couple of performances, get something out of the game, then hopefully we can finish the season strongly."
