Barcelona are ready to move for Real Sociedad striker Alexander Isak if they fail in their bid to sign Borussia Dortmund's Erling Haaland this summer.

Club president Joan Laporta is close with Haaland's agent, Mino Raiola, and hopes to use that to his advantage, but the reality is that Barcelona's delicate financial situation may leave them unable to afford such an expensive deal.

Other suitors, like Real Madrid, Manchester City, Paris Saint-Germain and Chelsea, are in better positions to make such an offer and the feeling is that Barcelona may struggle to compete for Haaland's signature.
