The forward, who impressed with Switzerland at Euro 2020, could serve as backup to main man Harry Kane next season.
If Kane's rumoured move to Manchester City goes through, Seferovic may even lead the line for Spurs next term.
According to the Daily Mirror, Spurs could secure Seferovic for roughly £20-£25 million, even though he has a buyout clause of £50 million.

The Portuguese, who left Wolves at the end of last season, is replacing his countryman Jose Mourinho, who was sacked in April.
