Bahrain Grand Prix Preview: Button is back
Jennie Gow and the 5 live F1 team are in Bahrain to get the latest on Alonso's move.
Jenson Button is set for a McLaren return, for one race only... Jennie Gow, Jack Nicholls and Tom Clarkson look ahead to the third stop on the F1 calendar, the desert of Bahrain.
Lewis Hamilton's victory in Shanghai last weekend ignited the battle, as the Brit is tied on points at the top of the Championship with Sebastian Vettel, who followed up his win in Australia with second place. The multiple world champions are on 43 points each.
The team discuss whether the battle in Bahrain will come down to a straight fight between the two, or whether the rapid Dutchman Max Verstappen could make it a three-horse race.
