Champions League finalists Borussia Dortmund and Bayern Munich are bitter rivals, yet in tactical terms they offer variations on the same theme.
.
Both press their opponents high up the pitch, can move the ball from defence to attack with bewildering speed and play with a 4-2-3-1 formation featuring wide players on each flank and a lone striker.
.
Dortmund, however, are more lightweight and lean towards a more counter-attacking style.
.
One of coach Juergen Klopp's training exercises involves setting his players a target of eight seconds between winning possession of the ball in their own half and having a shot on goal.
.
Pressing their opponents is a key to Dortmund's style, so much so Klopp once described it as "the best playmaker a team can have".
.
Yet, even Klopp has realised that you can have too much of a good thing.
.
He admitted his team tried to do too much in the Champions League last season, when they pressed their opponents relentlessly and dominated matches only to finish bottom of their group behind Olympiakos, Arsenal and Olympique Marseille.
.
This season, Dortmund have pressed in shorter bursts, yielded possession to their opponents, yet have been ruthless in the counter-attack and finishing.
.
The addition of the lithe Marco Reus on the left flank has been fundamental to the new approach.
.
"I have learned a statistic," Klopp told uefa.com.
.
"Teams that run too much lose, and teams that press reduce their chances of winning the game. Now I know why it happened.
.
"We ran more than our opponents and we pressed them all over, as high as possible."
I am sure they would give us a fantastic final to watch. I trust them to play quality football.
