Cristiano Ronaldo has a touch of double vision - but could hardly be happier.

Manchester United's gifted winger is in sight of retaining the Barclays Premier League title as well as lifting the Champions League trophy.

Ronaldo ended a five-game run without a goal with a timely reminder of the art of scoring in the 4-1 trouncing of West Ham.

He grabbed a brace with former Hammers Carlos Tevez and Michael Carrick also on target.

Dean Ashton pulled a goal back before United were reduced to 10 men when Nani appeared to headbutt Lucas Neill.

But even that petulant action could not take the gloss off a polished performance by the team - and Ronaldo in particular.

He took his tally for the season to an astonishing 40 goals with 30 of them coming in the league.

Ronaldo, the PFA and Football Writers' Player of the Year, needs only one more to equal Alan Shearer's record of 31 in 38 games.

Ronaldo was unplayable at times against the Hammers as United showed not the slightest trace of a hangover after beating Barcelona in midweek.

That saw Sir Alex Ferguson's side book their place in the final of Europe's top club competition against Chelsea.

The Portugal international said: "It is wonderful to score so many times. Now if we win the next game we are Premier League champions.

"We are also in the final of the Champions League, so all the players are very excited and very happy as we have a great chance to win both.

"I have to thank my team-mates a lot as they give me great passes. If they give me an opportunity, I am confident I can score."

The pressure is back on Chelsea, now three points adrift, when they face Newcastle on Monday at St James' Park.

Defeat is not an option for coach Avram Grant given United's vastly superior goal difference - plus 56 compared to 37.

United are in the driving seat and finish the campaign at Wigan next Sunday while Chelsea entertain Bolton.

It is a fascinating climax to the season but Owen Hargreaves believes there should be only one winner.

"It would be nice if teams like United who play attacking football and score lots of goals got their reward," said the England midfielder-turned-right-back.

"It is very rare at this level to see a team at the top of the table with such a massive goal difference.

"We are in control of our own destiny, which is what you want, and we need only one win to retain our title.

"Now we will see how Chelsea get on. It should be an interesting game as Newcastle are doing well of late."

Hargreaves was pleased with the way United reacted after the euphoria of beating Barcelona.

He said: "We got three goals very quickly and then West Ham got a goal back.

"Perhaps we could have defended better and when Nani got sent off it made things a bit more difficult.

"But West Ham surprised us by the way they defended and we kept the ball better than them.

"I thought we were always likely to score again as we maintained our focus and that's what happened.

"It was important to finish our home game with a win as there was good energy among the supporters."
