Ireland Pens Loan Deal
The 24-year-old Irish international arrives from Aston Villa, who he joined in the close-season from Manchester City.
Speaking to .co.uk, Pardew said: 'Stephen has shown over the past few seasons that he's a real top player so we're really pleased to have got him until the end of the season.
He can create chances for others and score goals himself, and we think he can be a big factor for us in the second part of this season.
I think Stephen feels he can deliver more than he's shown at Villa so far, so he's got a point to prove and I believe we can reap the benefits of that.'
TOTT have one word - underwhelmed!
