Ferrari driver Fernando Alonso has slammed Formula One’s rules on car testing, describing the regulations as like asking footballers to train with tennis balls or tennis stars to play with bats.

F1 is one of the very few sports in which training is forbidden … It’s like telling Lionel Messi to train with a little tennis ball or Rafael Nadal to play with a ping-pong bat…We go karting because we have no alternative.
