Watford winger Richarlison is already attracting interest after a terrific start to the season.
Richarlison would be a tremendous addition for Spurs who lack a quality winger, but they should be wary of potential interest from Manchester United.
Richarlison's form in Brazil for Fluminense caught the eye, where he scored seven goals in 21 appearances before his big move to Watford.
Manchester United were keen on signing Ivan Perisic from Inter but failed to land the Croatian, much to the frustration of Jose Mourinho.
This has left the Red Devils short of a winger, and Richarlison can still fill that void.
The way it has worked out could actually be good for United, as they have been able to see if Richarlison can adapt to the Premier League - which he has at Watford with huge success.
It will cost them more now to sign him, and there is more competition, but if they were tentatively keen in July, they should be more determined to land him now.
Tottenham will provide stiff competition for the Brazilian, with Mauricio Pochettino's record of giving young players a chance potentially working in their favour.
Richarlison is still just 20-years-old, and with a move to either club, could raise his profile and gatecrash Brazil's 2018 World Cup squad.
A tug-of-war over his signature would not be surprising at all, with Watford stuck in the middle.
