Newcastle United are chasing a deal for Fiorentina striker Dusan Vlahovic.

The Sun says Toon's top spies watched the hitman in action as his country qualified for the World Cup by beating Portugal.

Vlahovic, 21, could be sold in January if the price is right.

The fee will be large but reports of £70million are over the top, according to those near the deal.

And as Newcastle will find it hard to land talent from Prem rivals, they are on extra alert for players abroad.

Manchester City and Tottenham are admirers of Vlahovic but do not have a desperate need to buy in the next window, while survival fighters Newcastle do.
