However, Dunphy isn't buying into the hype surrounding Pogba, claiming the midfielder doesn't vastly improve United, who trail Manchester City by eight points in the Premier League. I can talk of what Paul brings - big quality.
The 36-year-old came on as a second-half substitute in the win over Newcastle, replacing Anthony Martial.

The enigmatic Swede has, however, been brought back into the fold after recovering from a serious knee injury and 1999 treble victor Cole - who operated alongside the likes of Dwight Yorke, Teddy Sheringham and Ole Gunnar Solskjaer during his time with United - believes added competition will prove to be a help rather than a hindrance.

"We believe we can do it". I don't think Pogba makes a great deal of difference and we will see when they play the good teams. I train hard. I sacrificed a lot.
