Pep Guardiola has a habit of managing dominant teams, but Bayern Munich's manager is wary of Manchester United causing an upset in the Champions League quarter-final second leg on Wednesday.
Despite being in charge of the current German and European champions, the Barcelona legend outlined the areas David Moyes' side could exploit at the Allianz Arena.
"United will be looking to hit us on the break and at set plays and we have to be aware of that," the Spaniard warned.
It was from a corner the 2008 winners opened the scoring last Tuesday, with Nemanja Vidic evading Bayern's defence to place a superb header past Manuel Neuer.
Danny Welbeck's pace caused the holders a few problems too, as the England international wasted a one-on-one opportunity in the first half.
He was slightly unfortunate to also have a goal disallowed, but Bayern are favourites, despite being winless in their last three games.
The weekend's 1-0 defeat to Augsburg should not have much relevance, but they have not won since retaining the Bundesliga title on March 25.
Guardiola has labelled the winner-takes-all match as a season-defining fixture.
"It's a final - a life or death match," he said.
Both sides have a history of dramatic contests, with Manchester United's stunning 1999 success and Arjen Robben's late tie-winner in 2010 shocking both sets of supporters.
That night Bayern progressed on away goals at Old Trafford, but you'd feel Pep wouldn't be too impressed if they went through in this fashion again.
