Both clubs are hoping to have a positive start to a well-balanced and competitive Group A, which also features Shakhtar Donetsk and Real Sociedad.

Assuming United takes care of business in today's match, Leverkusen is in stored to find themselves in a very tight battle for the berth in the Round of 16.

United boss David Moyes recently challenged Wayne Rooney to score 30 goals this season and has already determined that he'd form a formidable partnership with Robin van Persie.

"I will try to do that. I think Wayne's aim will be to do that as well. Hopefully we can make that happen" he said.

Moyes also believes the pairing of Rooney and Van Persie can pose problematic for opposing defenders.

"The hope is that we get a partnership where folk are saying 'My goodness we are having to play against Robin van Persie and Wayne Rooney'. Everybody is looking to see if those two form a partnership that can score lots of goals. I have to say I have also got Chicharito [Javier Hernández] and Danny Welbeck. Danny has made a great start to the season."

Last season Rooney managed 16 goals for United since being moved to a new position since Sir Alex Ferguson managed the club. However, under Moyes it is believed that Rooney will not be played in the midfield, thus the targeted 30 goals for the forward.
