Chelsea owner Roman Abramovich is threatening Manchester United's hopes of landing Borussia Dortmund striker Robert Lewandowski. The Telegraph says Abramovich is set to make a personal check on Poland forward Lewandowski during Russia's Euro 2012 clash with the co-hosts in Warsaw.
Also in his sights will be Lewandowski's Dortmund and Poland teammate Lukasz Piszczek, whose agent had contact with Chelsea earlier this year.
