Lampard: Chelsea firepower too much for Arsenal
"It's a massive game for us, Arsenal have been fantastic this season. They've slipped up a little bit in the last couple of games, which happens to everyone, so it's a great opportunity for us to try and narrow the gap even more.
"But Arsenal are a fantastic team, especially at home, and we'll have to be at our best.
"It's virtually impossible to go through unbeaten nowadays. It's not tiredness, it just seems like things are going against them."
