Philippe Clement has highlighted a baby boom among the squad at Ibrox amid some tired performances by his players.
The Belgian was unhappy with his side after last night's 1-1 draw at home to Aris Limassol in the Europa League.
The result leaves the Ibrox side needing a win on the final group stage matchday, which comes away to Real Betis in a fortnight.
The manager didn't mess about as he substituted Todd Cantwell after just 35 minutes. His replacement, Ross McCausland, netted the equaliser for the Glasgow giants.
But it's not just on-field matters Clement is keeping a watchful eye on. He's revealed that there are a number of players in the first team whose partners have given birth recently or are due to have a baby in the coming weeks.
Clement reckons the baby boom has had an impact on some of the performance levels of his players dropping off, as he cited Abdallah Sima.
He said “I’ve seen Sima in the last few games a little bit at a lower level after the birth of his baby, some less sleep and maybe the occasion. We have had a few interesting weeks in that way with players who have been injured.
"Or players who are getting babies - there are quite a few in December and January. Those are things to look towards because we need everyone at their top level."
Meanwhile, Derek McInnes delivered a frank summary of Rangers' performance levels as they stumbled to a 1-1 draw at home to Aris.
The former Rangers midfielder - who played at Ibrox between 1995 and 2000 - reckons his old club was below par on the evening.
He told TNT Sports: "I thought Limassol were average at best. Rangers at their best should wipe the floor with this team. Maybe it just illustrates that Rangers aren't quite where they need to be."
