Mikel Merino could be set to make his Arsenal debut against Paris Saint-Germain.
The 28-year-old Spanish midfielder joined the Gunners from Real Sociedad for £33million in August.
But he then suffered a 'small fracture' to his shoulder during his first training session with his new club. Merino has so far missed six games with this injury but he recently returned to training.
He was also spotted on Tuesday afternoon with the rest of the Arsenal squad attending a pre-match meeting at a Hilton hotel in London.
A video posted to X (formerly Twitter) by Connor Humm showed Merino signing autographs for Arsenal fans before walking into the hotel
