Former Chelsea boss Graham Potter was spotted at the Emirates to watch Arsenal's clash with Crystal Palace.
The 48-year-old was sacked by the Blues last April after struggling during a dismal seven-month spell with the west London club.
Amid uncertainty over the future of Eagles manager Roy Hodgson, Potter was a notable attendee in north London.
Hodgson has found himself under pressure at Palace with his side currently sat 14th in the Premier League table.
The south London club also crashed out of the FA Cup in the third round this week after a 1-0 defeat by Everton.
Open vacancies in the Premier League have been hard to come by this season with the only dismissals taking place at Nottingham Forest and Sheffield United.
But Potter will be hopeful of returning to the touchline sooner rather than later after a 10-month break from football.
In late November, Potter was thought to have been offered the job as Sweden's national team coach, after previously enjoying a successful stint with Swedish outfit Ostersunds.
Potter lead Ostersunds to three promotions in five years, and oversaw their Swedish Cup victory in 2017.
The club then embarking on a memorable run in the Europa League, where the club reached the knock-out stage before eventually falling to Arsenal.
Potter has also been linked with the Manchester United job in recent months to replace the under pressure Erik ten Hag.
Reports in December suggested new part owner Sir Jim Ratcliffe met with Potter before his investment was announced as he rates him highly.
