Serge Gnabry has warned Chelsea that Bayern Munich won't allow them to mount a Liverpool-style comeback in their Champions League round-of-16 second leg.
But after seeing Liverpool fight back from the same scoreline to beat Barcelona 4-3 on aggregate last season, former Arsenal player Gnabry said postmatch that Bayern won't let up.
"Three goals should give us a lot of confidence," he said. "We need to be prepared for the second leg and we can't take it serious enough.
"We saw last season with Liverpool beating Barcelona, we know we have to be careful and focus."
The German champions, clearly a class apart from their hosts, piled on the pressure from the start of the match and bossed Stamford Bridge with flair and 63% possession.
"It was a really good result for us," Bayern coach Hansi Flick said. "The team performed exactly how we planned and we were very focused how we played."
A smiling Flick said he was very happy Gnabry was now plying his trade in Germany rather than England.
"I saw how he played at Arsenal and I followed his career intently," Flick said.
"You could tell what he could do for the first Champions League match I saw him... he really impressed me and with Bayern Munich he's really developing well. So I'm very happy that he's playing with us."
Despite the daunting challenge, Chelsea manager Frank Lampard said his team will vow to fight on March 18 at Allianz Arena.
"In the bigger picture we saw there is a lot of quality in their team," Lampard said after the match. "There is a lot to them. But we can't look back on anything.
"We are fighting for the top four [in the Premier League] and we have to go to Munich and show a lot of pride. I will keep working."
Lampard added that his players need to use the loss as "positive effect."
"It might not feel like it this evening. A lot of players there haven't played it, or maybe a few years ago. When you have an eye opener the only answer is to just look at yourself."
