Tottenham have been warned they've not yet won anything in terms of Champions League qualification.
Fourth spot does not guarantee that much.
The top three go straight into the group stages.
All fourth earns is a place in a two-legged play-off round in August and Lyon could be a possible opponent in an open draw.
Newcastle went out to Partizan Belgrade before the group phase in 2003 while Everton crashed to Villarreal five years ago.
But Spurs could still catch rivals Arsenal for third and avoid a play-off.
