I'm a little surprised what caused Tottenham to experience a decline in performance, losing 2-1 to Newcastle was really beyond prediction. I bet for them in this match but it's really unlucky. MU and Chelsea's points are getting closer to them, there is a possibility that their position will be shifted if they continue to lose.
Tottenham should have been able to beat Newcastle but maybe there was a movement that made Tottenham's defense weak and read by the coach from Newcastle so they took advantage of that to score the second goal, Newcastle had not many chances but they managed to take advantage of it and get a win against a great club like Tottenham.
