Borussia Dortmund striker Robert Lewandowski has dismissed suggestions that he will join Manchester United in January.

The 24-year-old was strongly linked with a move to Old Trafford in the summer and in the wake of Sir Alex Ferguson's visit to the Etihad Stadium to watch him against Manchester City in the Champions League earlier this month, he has once again come under the Red Devils' radar.

"I'm playing in a serious league so he can watch me every week if he likes," Lewandowski is quoted as saying in The Daily Mail.

"But I have two years left on a valid contract with my club and I want this season to be as good as last season."

Lewandowski joined Dortmund from Lech Poznan in 2010 and won the Bundesliga title in 2010-11 and 2011-12.
