Evans said: "I know Danny well. We've played together for United since we were 12 and we lived together for five months at the end of last year when we were both at Antwerp .
"We spoke last week and he said that he wanted to get out on loan if possible because there were plenty of fit players at United and he didn't think he'd get much of a chance other than the reserves.
"Then he phoned me the other day to say Sunderland had been in and I was telling him what it was like up here.
"I told him about us taking 6,000 fans to Sheffield Wednesday last weekend and that I've enjoyed it here."
"Danny will never let you down," said the Northern Irishman. "He's a really honest lad, quick, good on the ball and quite strong.
"I've not seen a winger get past him. Defensively, he's a natural, but he likes to get forward.
"When we were at Antwerp he was complaining because a lot of teams over there play three up front and he had to stay back a lot."
