I think it is all over blown to be honest. I know I'm a Spurs fan so I am more biased but last season during the CL stages they played half the games with Aldy and Kane. Two huge leaders. Also Monaco were much better than people thought.
Losing the tie to Gent was embarrassing but they still drew the 2nd leg at Wembley vs them playing with 10 men once Dele was sent off.
The FA cup semi-final loss was actually a good match they played. Chelsea were just better. Same with last week.
People like to say they struggle at Wembley, which they do but it's not because it's Wembley. It's because they are always playing good teams when they are playing there. The quality of play is usually pretty good.
