Nketiah extends arsenal scoring record against portsmouth
I think there may be a mistake here!
Eddie Nketiah is a talented young striker for Arsenal, but I'm not aware of him extending Arsenal's scoring record against Portsmouth. Portsmouth is a lower-league team that has been relegated to League One, and Arsenal is a top-flight team in the Premier League. It's unlikely that Arsenal would be playing Portsmouth in a competitive match, let alone one where Nketiah would be extending a scoring record.
If you could provide more context or clarify what you're referring to, I'd be happy to help!
