Arsenal boss Mikel Arteta accepts his side must strengthen in the transfer market if they are to become Premier League champions next season.
Arteta’s side were beaten to the 2022-23 title by Manchester City.
The Gunners have been linked with a move for West Ham midfielder Declan Rice and are also closing in on forward Kai Havertz from Chelsea.
“Next season is going to be the toughest league in Premier League history,” said Arteta.
“Why? It already was last year. I’ve been here [England] for 22 years and I’ve never seen a competitive level like that. So much quality, so much organisation, so many resources, so many good coaches.
“That’s the level and to win the Premier League you have to be the best. That’s why you have to strengthen.”
