Germany boss Joachim Low believes that next year's Bundesliga title race is by no means a foregone conclusion.
Bayern Munich won the league at a canter last season, finishing 25 points ahead of their nearest rivals Borussia Dortmund, whom they also beat 2-1 in the Champions League final.
With the arrival of Pep Guardiola and Thiago Alacantra, many have tipped Bayern to win a second successive title.
However, Jurgen Klopp's men have also added new faces, with Sokratis Papastathopoulos, Henrikh Mkhitaryan and Pierre-Emerick Aubameyang joining the club, and Low believes they will challenge Bayern.
"Of course, Bayern go into the new season as the favourite, but I always trust that BVB can annoy FCB," Low told Sport 1.
Joachim Low has taken the national side to at least the semi-finals in the three major tournaments since his appointment in 2006.
