Verstappen and Alonso back where they first and last won

Max Verstappen took his first grand prix win at Barcelona's Circuit de Catalunya with 33 on his car in 2016 and the same number will be a focus for Fernando Alonso fans when the Spaniard returns to the scene of his last victory.

His 32nd win was with Ferrari in May 2013 and Sunday's race could be emotional.

If the heart beats for Alonso, with even Verstappen admitting in Monaco last weekend that he would love to see his fellow double champion win again, the head points to Red Bull's runaway championship leader.

Red Bull have won every race this season and the Dutch 25-year-old, who now has the champion's number one on his car, has taken four of the six.

Mexican team mate Sergio Perez has won the other two but is 39 points adrift after failing to score in Monaco.

The big ongoing questions are whether Red Bull can do the unprecedented and win all 22 races this season, whether Verstappen will take more than last year's 15 victories and where the third title might be won.

Some would add "can Perez fight back?" but history offers little encouragement once Verstappen has got going.

Verstappen won in Spain in May 2022, when the race was the sixth round, to take the overall championship lead and he has not relinquished it since.

For Alonso, runner-up in Monaco after four third places in the other five races, another podium finish has to be the target.

"We have scored lots of third places, a second place in Monaco and the next one we need is the top
