The Polish forward has been out of form recently, and Hummels felt liberated after winning for the first time on six matches with club and country
Robert Lewandowski's performance against Wolfsburg was hailed by Mats Hummels after the striker scored twice and set up another to help Bayern Munich end their winless streak.
Bayern halted a run of four straight games without a victory in all competitions to relieve some of the mounting pressure on Niko Kovac, Lewandowski grabbing a double before turning provider for James Rodriguez to wrap up a 3-1 victory.
Lewandowski ended his own barren scoring run in the Bundesliga stretching back to September 22, but Hummels insists that the Poland international has been playing at the top of his game throughout the campaign.
