Alf-Inge Haaland took to social media to aim a dig at Arsenal minutes after the Gunners defeated Manchester City and his son 5-1.
In response to mass celebrations at the Emirates, Haaland Snr wrote: "«This Team» that wins everything. Ehhhhh, not."
The message was in reply to the official Arsenal account, who posted a photo of Myles Lewis-Skelly's contentious celebration which was captioned: "THIS TEAM".
The City striker, who equalised at 1-1 before goals from Thomas Partey, Lewis-Skelly, Kai Havertz and Ethan Nwaneri, was also spotted pointing to his Premier League champion badge on the side of his kit at full-time.
That was seemingly a pointed message that Arsenal have not won a league title since their Invincibles season of 2003/04, with City winning six of the last seven seasons.
But this time Arsenal took the spoils in an edgy encounter, sparked by a brawl in their previous meeting centred around Haaland himself, when he clashed with Gabriel and Lewis-Skelly.
That rivalry was renewed once again when the Brazilian centre-back was seen celebrating in Haaland's face when Martin Odegaard gave the hosts the lead in the first half.
Haaland could be forgiven for thinking he was en route to making Gabriel look silly with that gesture, rising high above William Saliba to meet Savinho's cross and equalise.
At 1-1, many would have thought that City were the more likely winners. But Haaland struggled for touches again and the Gunners took control of the second half.
