Ryan Taylor isn't by any means a safe option. You are blinded by two great goals. We don't know how well he will play, but he won't be much worse than Raylor. No way. He's a fantastic talented player with great speed, and experience from Champions League and Serie A. This QPR game is perfect for him.
That said, I will understand if Pardew, because of Santon not having trained enough, starts him on the bench.
