Jurgen Klopp has allayed any fears over Virgil van Dijk after the Liverpool defender limped off during Saturday's win over Southampton.
The Netherlands captain suffered a knock to an already bruised rib just after half-time in the 3-0 victory against his old club and was replaced by Joe Gomez.
After seeing his side make it six wins from six to head to the top of the Premier League table, Klopp was asked about the fitness of his Dutch defender.
The German boss said: "He already had a bruise in the ribs before the PSG game, which is very uncomfortable and he got another hit there.
"It's not cool but should not be too serious. It should be absolutely OK, hopefully. I didn't hear anything different."
Liverpool maintained their perfect start to the season thanks to an own goal from Wesley Hoedt (10), Joel Matip's header (21) and Mohamed Salah's close-range strike (45+3).
