Mikel Arteta has praised the professionalism of Bernd Leno as the Arsenal goalkeeper continues to provide high-quality cover for Aaron Ramsdale.
The 30-year-old is set to play at Crystal Palace with the Gunners continuing their push to consolidate a top-four place.
He had been first-choice, after moving to north London, since 2018. But following a poor start to the season, Arteta handed new £30million arrival Ramsdale a chance.
