Arsenal star a major doubt to face Newcastle United - has suffered a setback in training

Arsenal forward Gabriel Jesus is a doubt for this evening's Premier League clash against Newcastle United after suffering a setback in training.

The Brazilian has missed the last four games after suffering from a knee injury and wasn't pictured in training ahead of the Magpies' visit to the Emirates Stadium.

Gunners boss Mikel Arteta said: We couldn’t resolve that as quickly as we wanted and he had a small reaction in training again. We didn’t want to take any more risks because he’s been out for quite a while and he’s a player that we need at his best and we decided to give him a few more days."

Arsenal welcomed back Fabio Vieira from a groin injury for their Champions League last 16 first leg defeat to Porto on Wednesday night. Takehiro Tomiyasu, Oleksandr Zinchenko and Thomas Partey could be the next to return.

"Let’s see," Arteta said when asked about Partey. "We have another session today. He’s been out for many, many months now. We need to really nail the timing of when he has enough in the tank to compete. But I think he’s very close."

Meanwhile, Newcastle boss Eddie Howe is hopeful of welcoming back Alexander Isak and Joe Willock, while Fabian Schar is fine after hurting his wrist during last Saturday's 2-2 draw at home to AFC Bournemouth.

“They've trained this week, it’s been good to see them back on the grass," said Howe. "It’s been a long time for Joe but he’s a huge player for us. It’s been great to see him back amongst the group, he’s a very popular member of the squad. Really pleased for him.

"With Alex again, a really important player, he’s trained well so we’re happy with both players. We’ll have to wait and see, we’ve got one more training session but I’ve been pleased with their progress."
