Newcastle's crushing defeat by Tottenham. Why did this happen?

[sofiko]

Newcastle, which performs very well in the group of death in the Champions League, will lose by a large margin to a team that has not been the leader of the EPL for a long time and has lost many points, because for me this match should have ended either in a draw or with a small win for Tottenham, although in fact the score is very large 4- 1 is too much for Newcastle. Don't you think so?
