Michel Platini told an Italian TV programme that VAR "doesn't solve problems" during matches, branding it "a load of crap".
Platini,refused to consider using the technology after he became Uefa chief in 2007. The technology is now used across Europe's top leagues as well as its most lucrative tournament the Champions League.
He was banned from all football activity by Fifa in in 2015 over a controversial payment of two million Swiss francs,that he received from the world governing body's then president Sepp Blatter.
Platini however, believes he could still play a role in football after his four-year suspension from the sport ended in October.
"At 64, I have the opportunity for one last adventure, but I have no room for error and I have to think about it," he said.
A triple Ballon d'Or winner, Platini had been expected to succeed Blatter as Fifa president in 2016 but fell spectacularly from grace a few months earlier.
Platini has always insisted he did nothing wrong. "At Fifa, they did not want me as president," he added.
