Carrick believes was vital in helping to secure the three points.
"You know what you're going to get [with Rio and Nemanja]. They know each other's games inside out, and with me in front you have that little triangle that we use to try and defend well and start counter-attacks from.
"It was a case today of doing the basics right and letting the front boys produce the quality. As it turned out it was Rafa who produced the quality! It could have been more in the end but we'll take what we got."
