Liverpool manager Jurgen Klopp said that "passion" had been the determining factor in his side's gritty 2-1 comeback victory at Crystal Palace in the Premier League on Sunday.

Liverpool fell behind to Joe Ledley's 48th-minute strike and then had James Milner sent off for two bookable offences, only for Roberto Firmino to level before substitute Christian Benteke won and scored a 96th-minute penalty.

Klopp gambled following Milner's dismissal, sending Benteke on up front alongside Firmino, and his punt paid off as the visitors secured a third successive league win that lifted them to seventh place in the table.

"You can try, but the rest is passion," the German told Sky Sports at Selhurst Park. "For defence, you always need more passion than formation.

"We changed to 3-4-2. That's what we tried, a little bit risky. Dejan Lovren had to be the right-back and centre-half.

"We brought on Kolo Toure to save the result at the end, but you take what you can get. We had moments to score, but now everything is OK.

"Football is like this. You make a plan at the end, but the lads did great. This is the third league win in a row. I can't believe how it feels -- really good, a big moment for us."
