Borussia Dortmund forward Marco Reus quashed any thoughts of his team winning the Bundesliga title after going down to a humiliating 5-0 defeat against rivals Bayern Munich on Saturday.
Six matches remain in the top flight this season and, although Reus acknowledges there could be further twists to come, the Germany forward maintains Dortmund must focus only on a grim post-mortem of an abject outing.
"We played catastrophically, we defended catastrophically," he told reporters. "I don't have an explanation for that. We [applied] zero pressure. Bayern was much better, we have to admit that. Nevertheless, we have to analyze this loss, we mustn't play like that against any opponent.
"It was once again a lesson for us because we just did not play as a team. The only positive is that we are only one point behind and Bayern also have two or three hard opponents in the next weeks. But we do not have to talk about the championship if we play like that."
Favre selected Reus in a central attacking role against Bayern, something the 29-year-old feels does not play to his strengths.
"Everyone knows that this is not my favorite position and that I do not want to play there," he added. "But that should not be an excuse. The coach has to decide that."
Lucien Favre's side is now a point behind champions Bayern at the summit after a nightmare outing where they were 4-0 down by half-time.
