Eddie Howe knows he has one of the world's very best forwards in his ranks at Newcastle United - but the boss is not about to put his feet up and rest on his laurels over Alexander Isak.

Alexander Isak has scored seven goals in his last nine Premier League games and Eddie Howe admits he is still pushing his star striker to improve even further.

Eddie Howe wants even more from in-form Newcastle striker Alexander Isak. The 25-year-old Sweden international took his goal tally for the season to 12 in the 3-0 Boxing Day win over Aston Villa at St James' Park, 10 of them in his last 10 Premier League games, after a challenging start to the new campaign.

Alexander Isak is rapidly turning into one of the most coveted players in Europe but Newcastle United will resist any attempt to lure him away with a record price tag in excess of £150 million put on the Sweden international.
