Wayne Rooney scored one goal and superbly set up another as Manchester United overwhelmed Middlesbrough to move to the top of the Premier League.

Ryan Giggs feels the injuries to have beset Manchester United in recent weeks have not disrupted the team.

United are currently without the likes of Gary Neville, Michael Carrick and Owen Hargreaves, and suffered further setbacks ahead of Tuesday's 4-2 win over Dynamo Kiev.

Sir Alex Ferguson saluted his in-form attack after Manchester United fired four goals past shell-shocked Dynamo Kiev.

Cristiano Ronaldo grabbed a brace and there were further goals for Wayne Rooney and Rio Ferdinand as United created chance after chance.

Two goals from Cristiano Ronaldo helped a dominant Manchester United to a comfortable victory at Dynamo Kiev.

Kiev's defence was poor. Actually to be blunt, they were awful for much of the match. They looked disjointed against a United side whose attacking wave of Carlos Tevez, Rooney, Ronaldo and Giggs were a cut above sublime.

UNITED recovered from an early scare to ease to victory over nine-man Aston villa. The home side had taken the lead through Gabriel Agbonlahor, but United big guns Wayne Rooney (two) Rio Ferdinand and Ryan Giggs ensured the Reds jumped back up to second in the Premier League table.

Ryan Giggs today moved a step closer to breaking the Manchester United all-time appearance record after signing a new one-year contract to keep him at Old Trafford until the end of next season.

The 33-year-old has played 727 matches for United since his debut against Everton in March 1991. Only Sir Bobby Charlton, with 759 appearances, has played more games for the club.

Ryan Giggs has paid tribute to Gerard Pique, Danny Simpson and Anderson for their contributions in the 4-0 victory over Wigan.

"Pique came in at centre-half and did a good job, and so did Simmo," Giggs told the club's official website.

"They got two assists really, so overall it was a really good performance from them both."

Manchester United's attacking trio of Carlos Tevez, Cristiano Ronaldo and Wayne Rooney put their side top of the table for the first time this season.

United suffered two more injuries in the first half when Nemanja Vidic and John O'Shea had to go off, two substitutions that disrupted the champions' impressive early rhythm.

Wayne Rooney's first goal of the season fired Manchester United to victory against Roma at Old Trafford. Rooney broke the deadlock with a sharp 15-yard finish after he was set up by Nani to leave United three points clear at the top of Group F.

Manchester United boss Sir Alex Ferguson is amazed by the way Ryan Giggs takes care of himself.

"Ryan is 34 in December and I don't see any deterioration in him. That is quite amazing considering he is a forward," he said.

"The way he looks after himself has a lot to do with it. He won't play in every game but he will be here next season.
