Gabe: Qualifying predictions: 1.Lewis Hamilton 2.Max Verstappen 3.Valtteri Bottas, Surprise package: Charles Leclerc/Esteban Ocon.

For what it's worth, I'm going to go out on a limb and suggest Hamilton and Verstappen will end on the front row. Which way around? Who knows.

PhilSlocombe: My qualifying prediction: 1.Lewis Hamilton 2. Valtteri Bottas 3.Max Verstappen.

Could today be the day Lewis Hamilton records his 100th pole in F1? He does love it here. The Briton has won the last four races around this track.

He's already the qualifying king. His century is inevitable but no less impressive.

This morning's session has set qualifying up perfectly. Lewis Hamilton, Valtteri Bottas and Max Verstappen have all topped the charts in one of the practice sessions.

Red Bull's Verstappen did so in FP3 with Hamilton second, suggesting we could be in for another episode in their title battle this weekend.

Don't forget, though, that the top 13 were split by less than a second earlier.

A straight fight between these two or can someone else spoil the party?

Max Verstappen and the Mercedes drivers look set for another close fight for pole position after the Red Bull driver topped final practice at the Spanish Grand Prix.

Verstappen was 0.235 seconds faster than Hamilton, with the two Ferraris of Charles Leclerc and Carlos Sainz splitting the seven-time champion from his team-mate Valtteri Bottas.

But there’s clearly much more to come from Mercedes, whose drivers set their fastest times on their second laps on the ‘soft’ tyre which is at its best on its first lap.

And they also barely improved later in the session when simulating qualifying from their lap times at the start of the hour-lone period.

Ferrari look in a strong position to head the fight behind the big two, with Lando Norris down in sixth in the McLaren, and running wide into the gravel at Turn 10 late in the session.

Pierre Gasly’s Alpha Tauri was seventh, ahead of the second McLaren of Daniel Ricciardo, the surprising Alfa Romeo of Kimi Raikkonen and the second Red Bull of Sergio Perez.

Fernando Alonso was he faster of the two Alpines in 11th, the second Alpha Tauri of Yuki Tsunoda separating him from his team-mate Esteban Ocon.

The field was very tightly packed - less than a second separated Verstappen fastest from Ocon in 13th.

It's all set up very nicely for this afternoon. Qualifying begins at 14:00 BST and we'll return for build-up from 13:00.

Until then I'll leave you with the thoughts of our F1 chief Andrew Benson...

If this is qualifying, we've got Max Verstappen and Lewis Hamilton on he front row, but also have Verstappen's team-mate Sergio Perez in 10th and Hamilton's team-mate Valtteri Bottas in fifth.

Can those midfielders get themselves ahead of the second Red Bull and second Mercedes? That would give us a nice straight shootout without the strategic play that the second driver can sometimes bring.

That's that. Bottas topped FP1, Hamilton FP2 and now Max Verstappen in FP3.

Qualifying could be tasty.

There is less than a second between Max Verstappen at the top of the charts and Esteban Ocon in 13th. Lovely stuff.

Alpha Tauri's Pierre Gasly and Yuki Tsunoda were pacey yesterday but neither are in the top 10 today.

Kimi Raikkonen remains a surprise eighth in his Alfa Romeo.

Four minutes to go.

Sergio Perez has been knocked down to ninth now. The two Ferraris follow Verstappen and Hamilton in third and fourth before Bottas in fifth.

Hamilton has just done a second lap on his soft tyres which was quicker than his first. That suggests he can improve but he's still behind Verstappen.

It's going to be so tight between Max Verstappen and Lewis Hamilton. They have been fairly inseparable all season so far. Hamilton did a better time on a second flying lap - which is unusual, and shouldn't normally be the case.

Verstappen goes fastest by two tenths. A lovely, lovely lap from the flying Dutchman.

I reckon we have battle on our hands this afternoon.
