The Ajax midfielder is certainly one to watch this evening.
Rafa Benitez convinced Babel to join Liverpool in 2007 for £11.5 million from Ajax, according to the Daily Mail.
Babel’s four-year spell at the club was mixed in terms of success and nowadays he is playing in the UAE and causing controversy on social media.
But he has also been speaking to De Telegraaf about tonight’s game, as a former Ajax man with experience of British football.
He believes that midfielder Davy Klaasen could be vital to Ajax’s chances and backed his former club for the win:
"Because Scottish defenders are not used to covering.
"When Davy is playing off the striker, he can play between the lines. Cover the central defenders do not see Klaassen, then Ajax creates space for the wingers to run actions behind the last line and creating chances."
The threat of Klaasen is very real for Celtic. He is likely to play as the advanced midfielder of a trio and will do his utmost to get beyond the striker at every given opportunity.
If Celtic, as Babel hypothesises, fail to match the running of Klaasen then this could very well be a bad start to their tough Europa League campaign.
