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.
I don't think Tottenham can keep that position with their current form; they've been playing very poorly since their match against Manchester United; their midfield is very open, and they lack a strong midfielder to control the ball; as a result, they lose possession very quickly, which is causing them to lose. We know how sharp and good their attackers are, but their midfield is very slow, and they will struggle to win a match with such performance.
