The Cameroon defender started again for Liverpool today.
The 27-year-old has started two Premier League games in succession for the first time this season after being named in Klopp's first XI again for the 4-0 win at Bournemouth.
Matip, who struggled at Burnley in midweek to some extent, was excellent today as Liverpool moved top of the Premier League table by thumping the Cherries.
The former Schalke centre-back was playing in the absence of the injured Joe Gomez, who is sidelined for six weeks with a leg fracture.
Matip is something of a rarely-seen figure on the pitch for Liverpool this season, and Klopp feels that his capacity to play well on short notice is testament to the depth in his squad.
"Look what Joel Matip did today, how good he was and he has absolutely no rhythm," he told the Reds' official website.
"That’s the life of a professional football player as well, he trains on the highest level and he’s not even in the squad sometimes.
"Then we need you, play, and then he had a difficult start against Burnley and plays that game and this game."
Bigger tests lie ahead for Matip and Virgil van Dijk as a centre-back partnership.
Klopp's side face Napoli in a must-win Champions League clash next week, before facing Manchester United, Arsenal and Manchester City in the Premier League between then and January 3.
It's a massive month for Liverpool and Matip will need to be at his absolute best, but the German manager seems confident in his player's abilities.
