Barcelona are eyeing Newcastle United striker Alexander Isak.

The Sun says Barca have the Swede under consideration for the summer market.

The Catalans believe the former Real Sociedad striker can be signed for £90m.

A source said: “Isak is emerging as one of the best strikers in Europe, and Barcelona have been scouting him since Christmas.

“They see him as a player who could come in and lead their line for the next three or four years and be a massive success.

"He has all the attributes and would be a superb signing.

“Although Isak is happy at Newcastle, the chance of a move to a club like Barcelona would be very difficult to turn down.

"Newcastle know they will need to raise funds in the summer which is why Barcelona are ready to make their move.

"And, at 24 years of age, his best years are ahead of him."
