Red Bull look to send message to Hamilton and Mercedes in Bahrain opener

Lewis Hamilton returns to Bahrain four months on from winning an 11th race of a dominant 2020 season knowing Mercedes have plenty of questions to answer from an exciting-looking Red Bull.

It was another season to remember for Hamilton in a campaign disrupted heavily by the coronavirus pandemic, the Briton himself contracting the virus late in the season and missing the second leg of a Sakhir double-header a week later.

By winning a seventh Formula One world title, Hamilton levelled Michael Schumacher's all-time record and also surpassed the legendary German for overall race wins (now 95), and he is now going in search of history.

But the evidence in pre-season suggests Mercedes are set for a titanic tussle with Red Bull, whose exciting line-up of Max Verstappen – the 23-year-old many are tipping to finally go toe-to-toe-with Hamilton – and Sergio Perez will be out to lay down a marker at the Bahrain International Circuit in Sakhir.

Many have suggested that F1's technical 2021 changes have redressed the competitive balance and certainly there was evidence to suggest as such at pre-season testing where Mercedes posted the lowest lap count of any team and Red Bull set the pace on two out of the three days.

We have been here before with Mercedes, though, where some have questioned whether their period of dominance – the Silver Arrows winning the constructors' championship seven years running – is finally over, only for the German manufacturers to turn it on when it matters.

This weekend should give us a clearer indication as to the strength of both teams, but that is by no means the only talking point on the grid...

LAST TIME OUT

Red Bull can certainly take heart from a strong end to the 2020 campaign, which saw Verstappen coast to victory at the Abu Dhabi Grand Prix, a race in which Hamilton finished third after returning from his absence due to COVID-19.

In that race, Red Bull were not necessarily favourites but beat Mercedes in a straight-line fight for Verstappen's second triumph of the season – his first coming in round five at the 70th Anniversary Grand Prix.

Perez can also take plenty of confidence from the fact he triumphed at this circuit for the Sakhir Grand Prix a week after Hamilton's last win of 2020, with a power issue in Abu Dhabi meaning his final outing with Racing Point ended in a whimper.

Valtteri Bottas finished second ahead of Hamilton on that occasion and the Finn knows he has a lot to prove against a strong-looking Red Bull line-up, while McLaren cars finished in fifth and sixth and are fancied for another strong campaign after finished third in the constructors' championship.

WHAT TO LOOK OUT FOR IN SAKHIR

There are plenty of sub-plots in play this weekend after a close-season of change in F1.

Most notable is the return of a legend and the arrival of a rookie aiming to emulate his great father.

Two-time world champion Fernando Alonso is back, racing for the rebranded Alpine Team – formerly Renault where the brilliant Spaniard won his two titles.

Mick Schumacher, son of Michael, has sizeable shoes to fill and will start his career on the biggest stage with Haas alongside fellow F1 rookie Nikita Mazepin.

Sebastian Vettel has a new home after ending his association with Ferrari and will race for Aston Martin, who are back in F1 for the first time since 1960, while the Scuderia signed Carlos Sainz Jr from McLaren to line-up alongside Charles Leclerc for 2021.

McLaren consequently turned to amiable Australian Daniel Ricciardo to partner Lando Norris, with the team starting 2021 12 podiums shy of 500.

TOP FIVE OPTA STATS

- Vettel and Hamilton are the drivers to have won the most races at the Bahrain GP (four), and have taken the most pole positions (three).

- In 2014, Mercedes recorded the first out of their 70 one-twos in hybrid-era qualifying in Bahrain (Nico Rosberg first, Hamilton second). The Germans have achieved 78 one-twos; they are two wins away from reaching Ferrari as the team to have secured one-twos in qualifying most often (80).

- Mick Schumacher will race his maiden grand prix in Bahrain eight years, four months and three days after father Michael's final appearance in Brazil 2012. Both will have started in F1 aged 22 years old, but the younger Schumacher will have done so seven months and 16 days earlier than his dad.

- Sainz will be the third Spanish driver to race for Ferrari. In his maiden race for the Scudería, Alfonso de Portago failed to finish in France (1956), but Alonso won in Bahrain (2010).

- Verstappen has retired three times at the Bahrain Grand Prix (four in Sakhir), more than any other race in his F1 career. The Dutchman has the chance to win back-to-back grands prix in F1 for the first time after 120 races.
