Arsenal v Tottenham: Premier League – live

Key events

I didn’t expect Spurs to go with a back three, but it makes sense that they have. Against the better teams, Frank’s Brentford often switched from 4-4-3- to 3-5-2 and they’ll want the safety in numbers in defence. But more than that, two central strikers gives Arsenal’s centre-halves a problem they don’t often have and, with Kudus breaking from deep, they might be able to create the overloads so painfully absent from their play last time out.

Arteta didn’t have too many decisions to make. Mosquera has been impressive so far, but in a game of this magnitude, it’s no surprise to see the more experienced Hincapie preferred. And given Merino’s scoring record when deployed as a striker, it makes sense that he continue in the role – though I wonder whether there was a temptation to try a winger through the middle. We don’t see it often, but Palace did it quite successfully in the middle of the last decade with Wilfried Zaha, Jason Puncheon and Yannick Bolasie, and when Mark Hughes was suspended for a crucial game at Norwich in 1992-93, Alex Ferguson resisted the temptation to play an extra midfielder, instead going with Lee Sharpe, Ryan Giggs and Andrei Kanchelskis – with devastating results.

Frank, meanwhile, changes his formation from 4-2-3-1 to, I think, 3-5-2. Coming in are Kevin Danso, the third centre-back andMohammed Kudus, back from injury, while Destiny Udogie, Rodrigo Bentancur and Wilson Odobert are also selected; Pedro Porro, Pape Sarr, Brennan Johnson, Xavi Simons and Randal Kolo Muani are all benched.

Arteta opts to replace Gabriel with Piero Hincapie, rather than Christhian Mosquera, while up front, Mikel Merino continues deputising for Victor Gyokeres. Gabriel Martinelli and Noni Madueke are both on the bench having been out injured.

I’ll write these down, then we can discuss what they mean.

Arsenal (4-3-3): Raya; Timber, Saliba, Hincapie, Calafiori; Zubimendi, Rice, Eze; Saka, Merino, Trossard. Subs: Kepa, Mosquera, White, Martinelli, Norgaard, Madueke, Nwaneri, Lewis-Skelly, Dowman.

Tottenham Hotspur (3-5-2): Vicario; Danso, Romero, Van de Ven; Spence, Palhinha, Bentancur, Kudus, Udogie; Richarlison, Odobert. Subs: Kinsky, Gray, Porro, Sarr, Bergvall, Simons, Johnson, Tel, Kolo Muani.

Mikel Arteta would make a good assassin. Reserved and meticulous, bellicose and monomaniacal, his remorseless relentlessness is exactly what you’d not want on your case if someone put out a contract on your life.

Yet, paradoxically, Arteta’s Arsenal lack killer instinct, unable to find in themselves the unbridled cruelty that wins league titles. Where champions find a way, so far they have faltered.

There are various reasons for this, insufficient verve and depth most obviously culpable. But there’a also a sense that Arteta’s intensity – the very thing that would make him such an effective contract killer – saps his team of the freedom they need to merrily mass-murder the Premier League.

And they will be feeling the pressure this afternoon, top of the table and leading Chelsea and Manchester City by three and four points respectively, with today’s game in hand. If they can win it, they will take a huge step towards claiming a first title in 22 years; if they cannot, all the old doubts will resurface.

But there is also pressure on Tottenham who, last time out, were devoid of attacking imagination, needing two deflections for their two goals before conceding a late equaliser in typically spursy fashion. There is no sense that Thomas Frank is on the cusp of something.

On the other hand, though, Tottenham have the best away record in the league and a burgeoning set-piece prowess that, especially in the absence of the injured Gabriel, makes them a threat in this match. Moreover, the North London derby is the country’s most reliably wild fixture and, just as Arteta is a precise and focused danger, so Frank is a windmilling dervish able to inspire in his players focused aggression previously considered beyond them. This is going to be good.
