A handful of esteemed players will be squaring up to erstwhile teammates when Brighton & Hove Albion square off with Arsenal at the Amex Stadium in Saturday's Premier League clash, most notably two key troops on the visitors' end.
By coming to an accord with their notoriously tough negotiators from the south, Mikel Arteta's side added Ben White and Leandro Trossard to his ranks and has overseen the development of both men into key figures in the Gunners XI.
In fact, White - whose transition from centre-back to right-back has gone about as smoothly as it could - is in line to make his 100th top-flight appearance for Arsenal at his old stomping ground, unless Arteta decides to rest him with Bayern Munich on the horizon.
Trossard - whose departure from the Seagulls was more acrimonious - seemingly has a better shot of lining up from the off against his former employers, with Bukayo Saka an injury doubt and Gabriel Martinelli's foot issue being carefully managed.
On the other end, however, Danny Welbeck - a man who shared an Emirates dressing room with Gunners boss Arteta for several years - is bidding to thwart the visitors' bid to regain top spot in the Premier League table, and history is on the 33-year-old's side.
Welbeck's affinity for goals against Arsenal
With rumoured Arsenal target Evan Ferguson nursing an ankle injury, Welbeck - who was only brought off the bench towards the end of Brighton's frustrating midweek draw at Brentford - should be reinstated to the first XI in Saturday evening's battle.
Starts against Arsenal usually spell success for the former England international, who has netted in four of his last five games against the Gunners when making the first XI, both for Brighton and Manchester United.
Before crossing the Old Trafford-Emirates divide in 2014, Welbeck scored in both of the Red Devils' meetings with Arsenal in the 2011-12 season, including the historic 8-2 demolition at the Theatre of Dreams.
The final gameweek of the 2019-20 season, when the 33-year-old was donning the Watford colours, also saw Welbeck strike and provide an assist, but he could not save the Hornets from relegation in a 3-2 loss.
Since arriving at the Amex, the ex-Arsenal attacker has seen his Premier League minutes limited against his old team - only getting 11 minutes off the bench in Arsenal's 2-0 win in December - but he started and scored in last season's Emirates EFL Cup triumph.
Can Welbeck break Arsenal's resilience on the road?
Without Welbeck in their first XI, Brighton fired 24 shots on the Brentford goal without success in midweek, setting a new unwanted record for their most attempts in a Premier League away game without finding the back of the net.
That goalmouth frustration came after Welbeck had drawn first blood against current leaders Liverpool with a scintillating early strike - his sixth goal contribution from his last 11 matches in the top flight, despite being in and out of Roberto De Zerbi's first XI.
However, the attacker's only home involvements in that time have been assists - albeit against London clubs in Crystal Palace and Tottenham Hotspur - and it has been 13 games since Welbeck last scored a Premier League goal at the Amex.
An Arsenal side seeking a fifth top-flight away clean sheet in a row - which would equal an all-time club record - should be encouraged by Welbeck's lack of recent punch on the South Coast, especially with the formidable William Saliba and Gabriel Magalhaes more than capable of going toe-to-toe with him physically.
Welbeck nevertheless ranks in the 91st percentile for shot-creating actions against other forwards in the big five leagues - an average of just under four per game - and given his penchant to strike against the Gunners, the end of the home drought could be nigh.
