The Germany international emerged from the bench to play a key role as his side came from behind to beat Wolfsburg on Saturday
Jupp Heynckes has paid tribute to game-changing Thomas Muller following Bayern Munich's last-gasp win over Bundesliga strugglers Wolfsburg.
Daniel Didavi's early opener had put the hosts ahead and, although Sandro Wagner levelled midway through the second-half, Bayern had to wait until the 91st minute for a winner - Robert Lewandowski converting from the spot after Arjen Robben had already seen an earlier penalty saved.
Muller's introduction in the 62nd minute proved a big turning point in the contest, and Heynckes says the Germany forward was key to Bayern's triumph.
