Mikel Arteta confirms disastrous Arsenal injury news as Tottenham receive quadruple boost ahead of north London derby

Gabriel, 27, has been central to Arsenal’s outstanding defensive record this season, with the Gunners conceding just five league goals in 11 matches. However, his injury during the international break will be a major reason for concern for Arteta. The manager confirmed further tests will take place next Wednesday, though early indications suggest a worrying layoff.

"Gabi is going to be out for weeks," said Arteta. "It's clearly a blow because he's our leader in our backline, and to me, it's never a positive thing. The good thing is that we have very good options, and people have to stand up now and do the job."

Reports via The Athletic indicate fears that the Brazilian could miss up to two months, ruling him out for the rest of 2025 and potentially all the way into mid-January. A best-case scenario would see him return after a month, possibly just before Christmas.

With Gabriel unavailable for Sunday’s north London derby, Arteta will turn to deputies Piero Hincapie and Cristhian Mosquera. Both defenders are under consideration for the crucial clash at the Emirates Stadium, a fixture that could have early implications for the Premier League title race. Riccardo Calafiori is also a doubt after withdrawing from Italy duty with a hip issue. The defender has not trained since returning to England, though Arteta confirmed he will be evaluated in Saturday’s final session.

"He has been carrying a few things," said Arteta. "He hasn't trained yet. Tomorrow we have another training session, let's see how he is."

Before the international break, Arteta was already without Martin Odegaard, Gabriel Martinelli, Kai Havertz, Viktor Gyokeres, Noni Madueke and Gabriel Jesus. Arteta has hinted that several of those could return soon, but timing remains uncertain. Odegaard is expected back in early December, while Jesus is on track to return in January following ACL recovery.

In stark contrast to Arsenal’s growing injury list, Tottenham head coach Thomas Frank delivered a series of positive updates ahead of Sunday’s derby. Spurs will welcome back Pape Matar Sarr, Lucas Bergvall and Randal Kolo Muani, all of whom trained on Friday and are available for selection. Sarr suffered a scare while on international duty with Senegal after limping off against Brazil, while Bergvall had withdrawn from the Sweden squad following further concussion checks. Kolo Muani, meanwhile, missed France’s qualifiers after picking up an injury in the 2-2 draw against Manchester United, but will feature against Arsenal wearing a protective mask. Mohammed Kudus, who missed Spurs’ last two matches, is also in contention to return.

"Pape trained today,” Frank said. "He's ready, available. Lucas trained today. Ready, available. Kolo Muani, yes. Trained today. Available, of course, has a mask [he] needs to play with."

Frank did, however, rule out Dominic Solanke, who is still recovering from an ankle injury that has plagued his season. Solanke’s last appearance came in August, and although the striker insists progress is being made, Spurs are unwilling to rush him.

On Solanke, Frank said: "Dom is not ready yet. I think he also had an article recently where he spoke about it. So we are very, as I said, the same. Very aware that when we put him out there, we want to be absolutely sure, as sure as we can be, that no setback going forward. So I'm comfortable he will soon be ready, but I will not put a timeframe on it."

There was further positive news for Spurs as Radu Dragusin, Archie Gray, Ben Davies and Kota Takai all returned to full training this week.

Sunday’s derby promises to be an exciting affair as Arsenal will be battling to protect their position at the summit despite key injuries, whereas Spurs will arrive with renewed energy as major players return. For a defence built largely around Gabriel’s presence, the timing of the injury is far from ideal. If the worst-case prognosis is confirmed, he could miss 15 matches across the Premier League, Champions League, Carabao Cup and the FA Cup.
