Lewis Hamilton is embracing the element of competition in the 2021 Formula One season after taking his 100th career pole in qualifying for the Spanish Grand Prix.

Hamilton tops the standings three races in having won two of them, victories in Bahrain and Portugal coming either side of Max Verstappen's triumph at the Emilia Romagna Grand Prix.

The seven-time world champion was involved in another tussle with his rival on Saturday, edging out the Red Bull driver to reach a notable personal milestone.

Hamilton was 0.036 seconds quicker than Verstappen at the end of Q3, with Mercedes team-mate Valtteri Bottas making up the top three 0.132s back.

The Briton is the first F1 driver to manage a century of pole positions, with his first coming back in 2007 in Canada. Racing greats Michael Schumacher (68) and Ayrton Senna (65) are second and third on the all-time list respectively.

He has managed 10 poles in five of the past six seasons, while his haul of 12 in 2016 is his best tally for a single year.

The 36-year-old has recorded 58 wins when starting from first on the grid, only failing to finish among the points on two occasions, albeit not counting for nine retirements.

And it is not only the milestone which has boosted Hamilton ahead of Sunday's showdown, but also the challenge presented by Verstappen, who sits eight points behind him in the standings.

"It's always difficult to assess in the moment but wow, I've been racing a long time and the 100 mark is something I don't think anybody and particularly me thought I would ever get to that number," Hamilton told a news conference.

"It's been so enjoyable and it's crazy that it is 100 and it felt like one of the first. That for me is even more special. There have been so many qualifying sessions, so many near misses, so many mistakes and so many moments of growth and I love how close it is between us all.

"I think that's great for the fans and I think that's exciting for me also. And also the people that are only just behind us."

For his part, Verstappen is confident he can push Hamilton all the way.

"It's difficult to predict at the moment. I think we were quite decent in the long runs but [Mercedes] looked strong," he said.

"We know that it's hard to overtake around here and to be following closely, but I'm always optimistic and positive that we can do a good job and have a good race, and I hope, of course, that it's going to be as close as today."

There was not so much joy for Verstappen's Red Bull team-mate Sergio Perez, who went spinning in Q3 and could only claim eighth.

He said: "I just felt a bit weak going into qualifying, and it was just getting worse and worse throughout.

"I had a bit of an issue with my [left] shoulder through qualifying, and I was just feeling bad, all the way through it. 

"I've been with the doctors from the team, and it should be all good for tomorrow."
