"Rotation? Absolutely, they know it".
Jurgen Klopp could not have made it any clearer early several weeks ago.
The Liverpool boss was speaking ahead of his team's match against Newcastle United, and indicated that changes to his line-ups were imminent.
While there have been tweaks in certain areas of the side since then, five stars have been ever present starters in the Reds' eight wins in the league.
Virgil van Dijk, Andy Robertson and Trent Alexander-Arnold are three of those at the back.
Mohamed Salah is another in the front three. And there is also Gini Wijnaldum in midfield.
Klopp arguably now has a bit of a dilemma on his hands ahead of the trip to Manchester United next weekend.
Earlier tonight, Wijnaldum was instrumental in the Netherlands' 2-1 win against Belarus in their Euro 2020 qualifer.
The Dutchman scored twice before half time - first with a smartly-taken header and again shortly after with a fine effort from outside the box.
It took his tally to an impressive six goals in his last 11 appearances for his country.
And it follows his vital - albeit hugely fortunate - winner for Liverpool away to Sheffield United at the end of September.
Wijnaldum played the whole game this evening, which came on the back of another 90 minutes against Northern Ireland in Holland's 3-1 victory on Thursday night.
In last month's international fixtures, Wijnaldum again had the full hit of both matches against Germany and Estonia.
Given those exertions - if there was to be another candidate ripe for some Reds rotation, surely Wijnaldum is at the head of the queue?
James Milner will be rested and refreshed after having the international break off. Naby Keita must soon be pushing for a start now he is back from injury. Fabinho is seemingly undroppable at present in the midfield anchor role.
It does not stop there. Jordan Henderson will of course be desperate to play.
Alex Oxlade-Chamberlain and Adam Lallana could potentially have claims to feature too.
But Wijnaldum played more minutes than any other Liverpool midfielder in the Champions League and Premier League last term, such was his importance to Klopp's engine room.
It already looks to be shaping up similarly in 2019/20 with Gini a key component of the Reds' table-topping start.
Klopp must now make the call whether to keep on pushing Wijnaldum after a hectic early phase of his season - or give him a breather for the clash at Old Trafford on Sunday.
Given that Gini has definitely found his shooting boots of late, that could well be the deciding factor as Liverpool look to maintain their advantage over Man City.
