The Tottenham Hotspur midfielder doesn't sound too keen on turning out in the colours of his side's rivals.
In his first season wearing the white kit since linking up with the club last summer after a move from MK Dons, the 20-year-old has racked up eight goals and 11 assists in 44 appearances in all competitions at club level.
He has also broken through into the England side for the first time alongside teammates Harry Kane, Kyle Walker, Eric Dier and Danny Rose, and scored on only his fourth appearance at national level in a friendly against France in November.
Not only has he become a star on the pitch, being nominated for the PFA Young Player of the Year award in his debut top-flight campaign, but his personality off it has also made him a hugely popular figure with the White Hart Lane faithful.
Whether meant in jest or not, there is no doubt that comment will elicit delight from Spurs fans for whom playing for Arsenal is just about the ultimate sin a footballer can commit.
Alli's form this season looks likely to help Spurs finally silence Arsenal fans' taunts by playing a part in Mauricio Pochettino's side securing a higher league finish than the Gunners for the first time in over 20 years.
Spurs are currently six points ahead of Arsene Wenger's side, albeit having played a game more than their rivals.
