Former Manchester United defender Rio Ferdinand has warned that it would be "lights out" for the rest of the Premier League if Liverpool complete the signing of Alexander Isak.

The ex-England star also eulogised over Liverpool's business this summer.

Despite already securing the services of Florian Wirtz, Hugo Ekitike, Jeremie Frimpong and Milos Kerkez, the Reds maintain an active interest in 25-year-old Swedish striker Isak, with the player having informed Newcastle that he would like to explore a move away from the club.

Isak is not on their pre-season tour of Asia either as speculation over a huge switch to Anfield intensifies.

Despite being an icon of Liverpool's greatest rivals, Ferdinand – rather than show any bias – couldn't help show his true colours as a football pundit and relay his real belief that Isak would help secure Arne Slot a second Premier League title on the spin.

"Liverpool's transfer window has been nothing short of exceptional so far.

It's been an outrageous transfer window, and if they get Isak – it's lights out for the Premier League," Ferdinand said.

"They've got a squad there, they've got a hierarchy, they look stable, they look solid.

It's gone too well and if they get Isak, it's over."

Liverpool are hunting for attacking reinforcements, particularly with Luis Diaz poised to join Bayern Munich.

We, to a degree, control what is next for him."
