Tottenham only need a draw and that is enough for Tottenham to end the season in fourth place, because even though for example Tottenham draw and Arsenal win and then their points are equal but Tottenham have the advantage in the number of goals. So, maybe it could be the worst result for Tottenham, whereas in reality we will not doubt the quality of Tottenham right now. So yes, victory is a very possible result for Tottenham because the opponent is not very strong, although we don't underestimate Norwich but still, statistically Tottenham are clearly better.
Why would Tottenham take the risk of a draw when they can end the season with a beautiful victory. Norwich are not the team, who can to compete in this match, unless they want to take the Champions League away from Tottenham before leaving the Premier League. Also need to understand that the match Arsenal with Everton may not be easy, though Everton is at the bottom of the standings, but they are capable of surprises.
