Tottenham are in pole position to finish in third place after Mauricio Pochettino’s side were 3-1 winners against Chelsea FC at Wembley last weekend thanks to goals from Dele Alli, Harry Kane and Son Heung-min.
Spurs are in third spot and two points ahead of Chelsea FC in the Premier League table, while Arsenal are in fifth place and a point behind Maurizio Sarri’s men after 13 games in the English top flight.
Arsenal finished outside the Champions League spots in Arsene Wenger’s final season in charge and Unai Emery lost to Manchester City and Chelsea FC in his first two games in charge at The Emirates.
However, the north London side have responded in style following a return of eight victories and three stalemates to mount a surprise top-four challenge.
Emery’s men will have the chance to make up ground on Tottenham at the Emirates Stadium on Sunday and Arsenal can hoist themselves above Spurs with a victory in the north London derby.
Former Gunners defender Upson believes Arsenal have an outside chance of a top-four finish but makes Chelsea FC and Spurs favourites to secure the final two Champions League places.
“Chelsea were so bad on Saturday they have come in for a lot of criticism, but I think it is wrong to say that game shows Sarri’s side have been found out,” Upson told BBC Sport.
“Jorginho has shown he can set the tempo for the way they want to play but I don’t think stopping him means you stop the Blues – they have far too many other good players for that.
“If sides press him, like Spurs did with Alli, you leave space elsewhere and – most of the time – Chelsea will be capable of capitalising on that.
“The biggest reason they did not do that this weekend was because of how good Spurs were – it was a day where Mauricio Pochettinho’s side were exceptional in and out of possession, and it is hard to stop them when they are in full flow like that.”
Upson added: “Along with Arsenal, all three clubs are battling for a top-four spot – and with Manchester City and Liverpool so dominant, it appears one of them will miss out.
“Who will it be? Well, in terms of their squad strength and players, I would say the Gunners are slightly behind Chelsea and Spurs at the moment but, in terms of getting results, they are definitely good enough to be in the mix.
“Emery is playing a big part in that. It is still early days for him but tactically he is so adept that whoever Arsenal are playing, they will always have a chance.”
