Liverpool put three past Leicester City on Monday evening in the final Premier League match of the gameweek.
After Tottenham lost to Aston Villa on Saturday, that win was enough to secure Liverpool a Europa League spot.
In terms of the Champions League, the Reds are just one point off Newcastle and Manchester United. However, both sides have a game in hand on Liverpool.
As a result, Liverpool need to win their final two games of the season and hope for slip ups.
Asked whether he was relieved to secure European football after a testing season following the Leicester tie, Klopp replied: “Massively. Six, seven weeks ago I didn’t believe it could happen. What we lacked at the time was obviously consistency.
“There was only one way for us to do it, by pretty much winning all of our games. It is crazy but that was the situation we were in. We knew before the game that we would qualify for the Europa League if we won the game, which is absolutely great from where we have come from.
On beating Man United or Newcastle to a CL space, the German added: “The rest is not in our hands but we know we have to win all the games until the end of the season to have a chance [of qualifying for the Champions League]. Our job is to keep the pressure on. It’s not likely, but if not then this is already better than we could have expected six, seven weeks ago.”
