Manager Jurgen Klopp has told Liverpool's official website that his players currently on international duty have been instructed to check in after their matches.
Plenty of Reds stars are away with their national teams this week, while Klopp flew to Tenerife for a warm weather training camp with the troops who stayed behind.
But with a hectic April looming, including a Europa League quarter-final tie with his former club Borussia Dortmund, Klopp has demanded that his players abroad check in to report their fitness after featuring for their nations.
“I told them that I want some messages and always a little check-up – ‘I’m fine, it’s OK’ – after the games especially," he told the club's official website.
“You can see a few games but you can’t see all the games, so you have to get all the information you can get and that’s what we want.
“Hopefully we get [some] very positive information and they come back healthy and we can start the finish of the season.”
Klopp is perhaps justified in his concern, given that his squad has been decimated by injuries at times this season.
Danny Ings and Joe Gomez have been ruled out for the season, while Christian Benteke, Divock Origi, Lucas Leiva, Roberto Firmino and Alberto Moreno are all sidelined at the moment.
The Reds sit ninth in the Premier League table, seven points behind fourth-placed Manchester City with a game in hand, and the German will need his best players to emerge unscathed from the international break if they are to bridge that gap.
