Here they assert that Tottenham Hotspurs is already having interest in bringing in DUsan Vlahovic if Harry Kane leaves. Tottenham seems to have entered the race wit hPSG as they are also interested. If it is true that Juventus is valuing Vlahovic at €70 million, the Kane transfer would flush enough money into their pockets to finance the Vlahovic deal with ease.
Its optional for Tottenham Hotspur in fighting race with PSG for signing Dusan Vlahovic, if reach done deal with interested teams want to sign Harry Kane actually Spurs will fight for signing Vlahovic. But if not any team have done deal with Harry Kane transfer fees almost 100 million euro I don't think Spurs want to sign dusan vlahovic because they have Harry Kane. Due €70 million fees transfer for Dušan Vlahović I think Tottenham Hotspur have enough fund due Bayern Munich proposal bid offer above €80 million, Spurs have fund left €10 million if interested to sign Dusan but Juventus not publish yet with their official announcement about how much transfer fees from Dušan Vlahović.
I don't think easy fighting race with PSG because they will offer highest transfer fees than Spurs and excited salary offering will make Dusan priority from PSG offering than Tottenham Hotspur.
