MotoGP World Champion Valentino Rossi has challenged Formula One World Champion Fernando ෴Alonso to a head-to-head battle, in three different types of motorsport, to prove who is fastest.

Rossi's challenge came in response to🍒 Alonso's claim that "Rossi might finish fifth or even get on the podium (in F1) but I could do the same in bikes if I was given enough time to practice."

Renault driver Alonso, the winner of last weekend's season opening Bahrain Grand Prix, has also p🐟reviously claimed that the Italian's high profile Ferrari tests have hurt the team's 2006 preparations.

"I'm glad that Rossi has tested with Ferrari because that means they have lost valuable time preparing the cars f𒅌or the show they put on," said the 24-year-old. "Let him come and drive. It will be good because there will be more media attention."

However, Rossi has now struck back in style - telling Alonso that, i🦂f the Spaniard r𒀰eally thinks he can get on the podium in MotoGP, then they should race each other on both two and four wheels to prove who is the ultimate motor-sportsman.

"I read that if Alonso is able to make some practice then he can put a MotoGP bike on the podium with me," Rossi, a five times MotoGP World Champion, told Motorcycle News. "Well, I think we should drive a Formula One car, a World Rally car🅷 and a MotoGP bike,💎 add the times together and then we will see who is the fastest."

As well as his tests for Ferrari, and his renowned two wh🧸eele🍸d skills, Rossi has also shown impressive pace in a Subaru WRC car, a world championship spec go-kart and a Maserati sports car - all in the last four months.
