Cornel Rapa v Luis Nani
Rapa (21) is one of the great hopes of Romanian football. He has five senior caps already and faced United's Danny Welbeck, Chris Smalling and Phil Jones in an U-21s game between England and Romania last year. He faces a sharper test tonight, though, from United's electric winger Nani.
Nemanja Vidic v Marius Pena
The 26-year-old Pena scored Otelul Galati's first-ever Champions League goal, against Basel last month. He will need to be ready for a physical buffeting from Vidic, who has seen off many centre-forwards far superior to Pena over the course of his time at the top of the European game.
Wayne Rooney v Sergiu Costin
After a difficult fortnight, how Rooney would love to rediscover his scoring touch tonight, especially with the Manchester derby on Sunday. He will hope to have the physical and positional beating of 32-year-old Costin, a foundation stone of the Otelul Galati side over the last five seasons.
