Arsenal v Nottingham Forest live: Gunners can return to the top of Premier League table with win

Saka's afternoon is over and is being replaced by Reiss Nelson.

SAKA BLOW:

The winger is having further treatment after going down off the ball. Marquinhos and Tierney are warming up.

It looks to be Saka's ankle that is troubling him. But he remains on the field.

CLOSE!

Martinelli's shot is cleared off the line by Lodi at the near post! Saka on the rebound with a volley puts it over and is still holding his knee.

Saka looks okay to continue.

SAKA INJURY CONCERN:

The winger is still hobbling from that Lody challenge. He is getting some treatment.

Awoniyi puts Lingard through on goal but Saliba is back quickly to deal with the danger.

Saka chips it to Tomiyasu whose volley is deflected over for another corner. This time, the visitors clear the danger.

The Gunners are well on top. From Odegaard's crossm, Jesus tees up Partey on the edge of the box but is charged down.

Forest with their first chance. Freuler's long-ranger is comfortably saved by Ramsdale.

From a corner Lingard slips, Saka plays it to Jesus whose curling shot inside the box goes narrowly over.

Martinelli threw himself at the ball to head it into the bottom corner. And there is a nice tribute to Mari in his celebration.

MARI UPDATE:

Some good news out of Italy. Pablo Mari, on loan at Monza, has been discharged from hospital following the knife attack in Milan.

Lody with a crunching challenge on Saka, he escapes a booking. It was a 'letting him know you are there' sort of tackle.

We are underway.

Five minutes till kick off!
