Mats Hummels criticizes Favre following disastrous 5-1 defeat

It was

Dortmund’s

third game in a row without a victory, and currently fifth in the table, the Swiss manager,

Lucien Favre

, might be in danger of losing his job.

Mats Hummels

openly questioned his boss’ tactics.

"We always try to play small and small through narrow spaces and have a huge ball-loss rate,"

Hummels told Sky Germany.

"If it works, it looks like nice football. But it rarely does. That requires too much skill."

"A lot went wrong today,"

the 31-year-old continued

. "We didn't play a good first half either, but we went into the break happy to be level at 1-1."

The German defender believes his side’s extreme carelessness in possession cost them the match, as they conceded three goals in 11 minutes.

"2-1, we gave the ball away. 3-1, we gave the ball away. 4-1, we gave the ball away, we kept giving the ball away."

Former Germany international also praised the opponents:

“They did an excellent job, like they have been the whole season,"

Hummels said

. "They had a good plan, were aggressive and determined. And we weren't."

Dortmund will face
