Munich - One final, two Bundesliga clubs, 22 gladiators: These players will determine the outcome of the 2012/13 UEFA Champions League decider between Borussia Dortmund and Bayern Munich at Wembley Stadium on 25 May. outlines the careers and key facts of the protagonists.

The background

Cut him, and he bleeds yellow-and-black: , son of Dortmund. Born in the city on 19 July 1988, he played as a youngster at Borussia for a while joining the Rot Weiss Ahlen youth programme when he was twelve. Six years down the line, Großkreutz was chipping in with a dozen goals as Ahlen won promotion to Bundesliga 2 and it was not long before Dortmund came calling to reclaim one of their own, signing the 6' 1'' attacking talent on a three-year contract in 2009/10. The arrangement has since been extended through to 2016, evidence enough of the management's evaluation of a player most often used off the bench.

Now 24, the three-time Germany international is particularly versatile, capable of slotting into virtually any position out on the park if needs be. In the final Bundesliga game of the season he even pulled on the keeper's jersey for the last few minutes against Hoffenheim after Roman Weidenfeller was sent off. The injury to Mario Götze has freed up a starting slot for Großkreutz in the Wembley showdown with FC Bayern, where he is likely to operate in an advanced role down the left.

Champions League key facts

• Kevin Großkreutz has played a part in nine of Dortmund's twelve Champions League outings this season. Of his five starting appearances, BVB won three and drew the other two.

• He came on for the injured Mario Götze after just 14 minutes in the semi-final return at Real Madrid.

• Großkreutz has not been directly involved in any Dortmund goal in the tournament, but his 84 percent pass-completion rate matches that of Götze and tops Marco Reus's 78 percent.

• He has won a healthy 64 percent of his defensive tussles and 46 percent of all his one-on-one situations. That puts him level with Jakub Blaszczykowski and ahead of both Götze (39 percent) and Reus (41).
