Bayern Munich fullback David Alaba says they're wary of Champions League newbies Leicester City.
Alaba is close to Leicester's Austrian defender Christian Fuchs.
"It was amazing," says Alaba to the Daily Mail. "Christian did an amazing job last season. What stories did he tell me? The first thing he said was there was an unbelievable party – I saw them celebrating on TV! – they wrote a new page in history.
"Leicester have a great spirit and they will do their thing again. They have made enemies of a lot of teams now, by that I mean everyone knows what they are capable of and what they can do. Everyone knows they need to be respected.
"They are dangerous. You cannot win a title if you are not a good team. You can win a final with luck but what they did over a season was not lucky. Nobody expected this story to happen, nobody thought it was possible to do in the Premier League. They did something amazing for football."
