Liverpool agree £125m deal to sign Alexander Isak from Newcastle on deadline day

Striker to undergo medical after British record fee agreed

Loyalty payment could take deal to as high as £130m

Liverpool have agreed a British record £125m deal to sign Alexander Isak from Newcastle.

The Premier League champions had a £110m offer rejected in August and since then the 25-year-old has not trained with or played for Newcastle, but in the final hours of the transfer window a deal has been reached to end the impasse.
