Pardew feels that Anita presence could be vital in the campaign's run-in now that Yohan Cabaye has quit.
He said: "I feel for him a little bit, suddenly looking around that midfield and not having those two, because that's going to lift you as a person and as a player.
"Vurnon has got it all on him at the minute.
"But he's a huge man - he's 6'5" at times for us - and he's going to need to get a bit bigger."
