Top Dutch boss Aad de Mos reckons Feyenoord will beat Celtic in the Champions League home and away because they play 'infantile football' and are at the same level as Rangers.
The Hoops travel to the Netherlands next week to start their Champions League campaign with a tricky game in Rotterdam against the Dutch cracks.
They also have to play Atletico Madrid and Lazio as they aim to qualify from the section.
But veteran former PSV Eindhoven, Anderlecht, Werder Bremen, Sparta Rotterdam and the UAE national team boss de Mos reckons Feyenoord should defeat Celtic twice in the group.
He said: "Feyenoord are capable of winning all of their home games.
"In the first game, they will play against Celtic, who will come and play infantile football, although they do have a cunning manager in Brendan Rodgers.
"But ultimately, they fall into the same level as Rangers. Feyenoord should beat Celtic twice.
"Also Diego Simeone at Atletico Madrid and and Maurizio Sarri at Lazio are scared of De Kuip.
"Both will approach these games with a set-up not to lose and try and play on the counter.
"My prediction is that Feyenoord will be higher than either Atletico or Lazio and finish second. Celtic will be last."
Meanwhile, Celtic could be hit by a hammer blow after it was revealed Liel Abada could be out for up to five months, with Israel boss Alon Hazan admitting he's gutted for the winger.
The 21-year-old was injured on international duty in training and was sent back to Celtic after playing no part in his country's Euro 2024 qualifiers.
He was originally thought to be out for a month with a thigh muscle strain, but reports in Israel have suggested he will go for a further scan this week and could be missing for up to five months, which would rule him out until next year and mean he would miss the entire Champions League group stages games.
And Israel boss Hazan accepted he feels terrible about Abada's setback.
He said: "The thing that bothered me most about the international week was the injury to Liel Abada."
