Arsenal welcome Burnley to the Emirates Stadium on Saturday afternoon.
Having recorded a 1-0 win over Newcastle United last weekend, the Gunners know that three points over the Clarets will put them top of the Premier League table - albeit for a couple of hours.
And Gunners head coach Unai Emery has revealed what he expects from Sean Dyche's side.
"It's going to be a very physical match and we need that adaptation physically to be strong," he told reporters on Thursday. We need our game plan with our structure, with our tactical positioning and then after with individual duels against them.
"They are very strong in the duels, they are very strong in their structure, with two strikers. They are going to demand a lot of us defensively, with their long balls especially.
"They're the best team that I saw in the last match of the last teams I saw with a lot of structure.
"They are very clear, very efficient with playing with that structure. Also they have players who play very well. If you let them play, they can build up with [James] Tarkowski, with [Ben] Mee.
"With [Ashley] Westwood and with [Jack] Cork, after with their two very good right and left wingers [Dwight] McNeill and [Johann Berg] Gudmundson.
"I respect their team a lot and I respect their coach a lot."
It was a 3-1 win for Arsenal in both meetings last season Emery has been handed a massive fitness boost ahead of the game.
Alexandre Lacazette took part in the training session.
The Frenchman hasn't featured since limping out of the Emirates Cup loss against former club Lyon last month and was an unused substitute against the Magpies last weekend.
The Gunners were put through their paces at London Colney on Friday afternoon ahead of the early kick-off on Saturday.
Four of the club's six summer signings were present.
Deadline day arrival David Luiz trained as did loan addition Dani Ceballos, club record signing Nicolas Pepe and Gabriel Martinelli, while youngsters Reiss Nelson, Bukayo Saka and Joe Willock were also involved.
