"If we can regain the momentum we had from the wins against Manchester United and Arsenal, we can get the right result against Newcastle.
"The way we've been playing – solid at the back and dangerous going forward – I can't see us losing many games if we can get back to those heights. We'll be getting together this week for one final push, and it's about regaining our intensity in training and taking it into match day."
Roberto Martinez's side have recorded impressive wins over Liverpool, Manchester United and Arsenal in recent weeks, lifting themselves out of the drop zone.
