The two Liverpool strikers have scored 16 goals in all competitions so far this season.
The midfielder told Sky Sports News: "They have been great this season. Sturridge has been great for England as well. The two of them link up really well and we have to be ready for that.
"We'll watch a few clips of them, but our defence has been great this season. It'll be a big game tomorrow, probably our biggest test in the Premier League this season and we have to make sure, especially as we're at home, that we take the game to them.
"[Suarez] is a great player and if I said we didn't want him I'd be lying. But Liverpool did well to keep him in the summer and he's been their best player this season."
The sides meet at the Emirates tomorrow evening.
