Neither side head into Wednesday’s London derby in the best of form, with just two wins between them since the start of February.
Slaven Bilic’s side have particularly spluttered in defence, conceding 18 goals in eight games, but remain an attacking force to be reckoned with, particularly with Andy Carroll having proven a formidable match for Arsenal in the past.
And Fonte believes that if West Ham can stop the rot at the back they will have the chances at the other end to claim victory in North London.
“It will be a tough game against Arsenal, but it’s a game that I think we’ll have opportunities,” Fonte said. “I think we’ll have good chances.
“We’ve been leaking a lot of goals ourselves recently, but if we can be solid and compact, and hopefully take chances that will come our way, I think we’ll give ourselves a great chance to win that game.
“Arsenal have been in a tough patch too, although there is no good time to play top teams like them. They have great, great players who can decide the game in one moment.
“They’re a patient team; they like to play intricate football between the lines and they like to find that killer pass. They have players who can play that perfect ball. They haven’t been as good this season as people expected, but they can still hurt you at any time.”
Arsene Wenger’s side were on electric form last time they met the Hammers, winning 5-1 at the London Stadium as Alexis Sanchez scored a hat-trick. However the two sides’ last meeting at the Emirates was far less successful for Arsenal, Cheikhou Kouyate and Mauro Zarate scoring in a 2-0 win for West Ham.
