Red Devils have been tracking the Pole for some time now.
Manchester United are said to be increasingly confident of signing deadly Borussia Dortmund front man Robert Lewandowski this summer, reports the Daily Mail.
The coveted Poland international has been with the Bundesliga giants for the past three seasons now, having signed for Dortmund from Polish outfit Lech Poznan for just 4.5 million euros on a four-year deal in June 2010.
And in the intervening three-year period the 24-year-old has proved himself to be one of the most lethal and prolific finishers plying their trade on the Continent, netting a remarkable 75 goals in 139 matches in all competitions for his club, including 54 strikes in just 98 league encounters.
As a result, new United head coach David Moyes now wants to bring the Pole to Old Trafford when the summer transfer window finally reopens once again for business on July 1, with the Scot hoping to be able to tie up a deal for Lewandowski before the Premier League champions depart on their summer tour of Asia and Australia in the middle of next month.
