It's a short hop east for the second leg of this Iberian double header. The familiar Circuit de Barcelona-Catalunya, new and improved! (supposedly)
This is the first time in seven years we're racing in Spain having not tested earlier in winter. Somehow this makes me slightly more excited than usual. Maybe this time things will be different?
Nevertheless, against the backdrop of a bubbling title fight, raging midfield battle and emerging talents, who couldn't be excited for Round 4 of the 2021 FIA Formula One World Championship.

The Circuit
Turn 10 has been reprofiled, providing a much faster corner speed and subsequently higher entry speed to the following turn 12.


Prognosis from Portimao
A crucial victory for Hamilton sees him retain the championship lead as Mercedes head to one of their most successful circuits in the hybrid era. 6 wins in the last 7 years, interrupted only by the teammate collision in 2016, which saw one Max Verstappen capitalise for his maiden victory. How time flies.


A reminder that Bottas was on pole in 2019 and missed out by only 0.059s last year, so should be in the mix again on Saturday. Perez is yet to make his mark on this season, but has another good opportunity to showcase his tyre-whispering skills at a track that has always been tough on rubber.
The key question is: which car is faster? Red Bull will be glad to see a moderately abrasive track surface again, and will be aiming to optimise their Portugal upgrades to better effect. But this really is Mercedes' stomping ground, so it's anyone's guess. A Saturday show from Red Bull followed by another titanic scrap on Sunday?

There's a new force towards the head of the midfield as Alpine gate-crashed the McLaren/Ferrari retro love-in to remind everyone that the Rossi-Budkowski-Brivio triple threat means business. After glimpses of his old self in Portugal, Alonso returns to his beloved home race, albeit without the sparkling support and adoring Asturian flags. He took his most recent F1 win here in 2013.


The key question is: can they keep it up? McLaren and Ferrari have both shown great versatility so far and the assumed wisdom says they'll pull clear again, but don't bet against an invigorated Alonso. Plus, there's another sizzling Spaniard on the grid who will be fighting Fernando for fierce national pride. The Chili versus the Samurai.
Elsewhere, Norris will be buoyed by his fantastic start to the year. It's 3-0 as far as his fledgling battle with Leclerc is concerned. Typically, Alpha Tauri has failed to make the most of their new season promise, but like the sister team will be happy to attack a more conventional circuit, especially considering Tsunoda has solid F3/F2 experience here.

Towards the back, Aston arrive with updates on both cars after middling progress in Portimao. It was middling too for Alfa Romeo after klutzy Kimi biffed himself out on lap 2. Both teams will be aiming for stronger Sundays and an outside sniff of points. Kubica's back for FP1.
Speaking of klutzy drivers, maiden wins and bygone victories, a Barcelona build up thread wouldn't be complete without an ever-present reminder of Williams' last top-step success. One of my favourite podium shots of modern times.

Success this weekend will be defined by points, not podiums, but after Russell's tumble down the order last Sunday, it may be a weekend to regroup for the Grove squad.
Haas, by contrast, has a modicum of optimism. Schumacher is making decent progress and managed to beat Latifi to the flag in Portugal. The familiar surroundings for both drivers and team will help their cause as they try to usurp Williams at the very back of the grid.

Finally, it's almost 25 years since Michael's first victory for Ferrari. With an outside shot of rain on Sunday, it's only fitting to remember that great drive.
Despite its reputation, Catalunya has given us some great memories. Here's to plenty more this weekend
