Guardiola guided Manchester City to their fourth consecutive Carabao Cup glory after beating Tottenham Hotspur on Sunday, thanks to Aymeric Laporte’s lone goal.
The Citizens are on their way to win a third Premier League title in four seasons under Guardiola and are still in the hunt for their first Champions League trophy.
The Spanish coach has now won 30 trophies in his managerial career making him the active coach with the highest trophies won in Europe’s top five leagues.
His tactical prowess and knack of winning titles have forced Redknapp to label him as the best coach ever.
“Is he the greatest ever? I personally think with the style of football he plays, how humble he is, the way he improves players, I think he is the greatest ever. Already for whatever happens from here,” the Englishman said.
“There was always that argument when he was at Barcelona that he had Messi, Iniesta, Xavi. But now everywhere he goes you see the progression, the improvement. And this year might be the most successful.”
“After eight games they were 14th in the league, everyone questioning whether they had lost their appetite and whether the players were not running for him anymore. He has proved that is not the case. They are on a 21-game winning run, which is frightening. To see them now, the PL is pretty much sown up. Wednesday now becomes huge for them, he knows the importance of that you can see it in his eyes.”
