Cristiano Ronaldo feels United's hopes of silverware will be massively aided by the return to form and fitness of Wayne Rooney.
The England striker, who has missed 10 games through illness or injury this season, made a match-winning return to action at Aston Villa last weekend - a display which bodes well for the Reds, according to Ronaldo.
"Everyone knows Wayne is a good player," he said. "He does not have to do anything to prove that. He came on against Villa and did very well.
"He looked sharp and good - that can only benefit us. We have a strong season ahead of us, so it is important Wayne is ready along with all the other players as well."
With Rooney back in the fold and United well placed in the Premier League, Champions League and FA Cup, Ronaldo is intent on topping last season's league title triumph.
"I believe we can do better this year," he said. "We have a good squad, with a fantastic group of players. We have a good chance of winning all the competitions, so why not think about doing that?"
