The 1987 Formula One World Championship
Portuguese Grand Prix
Can Britain's NIGEL MANSELL upset the Brazilian one-two at the top of the drivers' championship?
The battle between PIQUET and SENNA continued in Italy two weeks ago and it seems only Mansell can interrupt it here. The Williams driver from the Isle of Man won this race a year ago and desperately needs a repeat performance if he's to catch the leaders.
