Bale, on-loan from Real Madrid, is suddenly shining for Spurs.
And Berbato told Betfair: "Look, we will never know what Mourinho's ways are like at Tottenham, how he motivates the players or how he talks to them in private, but I'm sure that in the resurgence of Bale, José has something to do with it.
"Let's see, of course everything depends on the player, it's true, but Mourinho is also part of that. He has worked with so many excellent footballers, so who better than José to help the great players get into their best form?
“It doesn't surprise me that Bale is back in shape with Mourinho, because he knows perfectly how to approach and deal with these things with Bale, how to manage his situation. He has been everywhere, won everything and managed the best."
