Klopp was quick to praise Henderson's display and admitted that he has been asking the England global to play out of position for well over a season.
In addition, Henderson chipped a ball to Firmino for another first-half chance and curled in an excellent cross after the break, only for Sadio Mane to be ruled narrowly offside after volleying into the net.
The Champions League quarter-final first leg at Anfield was not short of talking points as VAR again took centre-stage.

It took Jurgen Klopp's men just five minutes to open the scoring as Keita got his second goal in as many games having waited nine months to open his Liverpool account.
However, that proved a luxury that Liverpool could afford to take as they look set for a second Champions League semi-final in as many years.

On a bitterly cold night at Anfield, Liverpool were well below their best and Porto deserve credit for a determined performance after going two goals down in 26 minutes. 2-0 is a really, really good result. "We scored two wonderful goals, we were in a lot of really unsafe situations".
"We have to go there, we have to fight, Porto will do everything to strike back but that's how it should be in the Champions League quarter-finals", added Klopp.
