Marco Reus is tipped as the next great star of German football, and is already setting the Bundesliga alight - with nine goals and six assists in all competition for Borussia Dortmund this season.
The 24-year-old winger has a release clause of 33 million in his contract, causing Europe's big guns to sit up and take notice.
Dortmund want to tie him to a new deal, and he has long maintained he is happy at the club, but while the clause exists - which presents very good value for him - a transfer remains very possible.
Manchester United are one side linked with him, and it has now been reported by James Ducker of The Times newspaper that David Moyes sent two of his staff, assistant Steve Round and coach Jimmy Lumsden to check him out in action personally on Tuesday night against Napoli.
So what did they see when they watched him in Dortmund's 3-1 Champions League win?
Well they can't have failed to be impressed - Reus scored one goal from the penalty spot, and assisted another, instrumental in turning over Rafa Benitez' visiting side.
He had five shots on goal, three on target, and created two goalscoring opportunities. Reus completed 80 per cent of his passes, which was the highest of any Dortmund attacker on the night.
Reus completed three successful dribbles, and got stuck in defensively too, with two tackles and one interception.
While he did not show his best in the recent friendly with England, nor in the two games against Arsenal. Reus remains an outstanding talent, and United would be lucky to get him.
