Michael Schumacher will give driving lessons to some of his rivals when he returns to action in Spain, according to Bernie Ecclestone.
"I think he's going to give one or two of them a driving lesson. He obviously wouldn't have decided to come back unless he thought he was going to be competitive and Michael is a competitive guy. He's always been super popular even though he won too many races and people said he was boring. He was never boring and he won't be boring now."
The seven-time world champion will race for Ferrari at the European Grand Prix, replacing the injured Felipe Massa. It will be the first F1 race for 40-year-old Schumacher since retired at the end of the 2006 season.
Ecclestone admitted Schumacher's return caught him by surprise.
"I think I was just as surprised as Willi Weber - his manager - he didn't know he was coming back either. I think it was Luca di Montezemolo that convinced him."
