"It's been a difficult season, there's no denying that, all season," he continued. "But the new manager has come in and I really like him. The way he handles himself and speaks with the media, he's been really good. It's probably more about getting through this season now and, hopefully, starting to implement his style more and getting players in to move the club forward."
Rooney, who turns 40 in October, is delighted to be lending his support to UNICEF.
"I'm really excited," he said. "Firstly, I think I've done a few things for Soccer Aid and always enjoyed it. The most important thing is raising money for children around the world. It's incredible work that they do. Last year, they passed £100 million, which is fantastic.
"To come back and play at Old Trafford as well, it's always an easy one for me to say yes.
"So please go out and buy tickets for the game. I'm sure a lot of different characters will be out there to watch. Some good, some funny. The game has always brought that. More important is helping the most vulnerable kids around the world. Being a father of four, [it's about] anything we can do to help. We go out and play the game and various things to help the charity, but it wouldn't work if the people at home didn't buy a ticket or contribute. Everyone has a major part in changing kids' lives."
