They're incredibly frustrating.
Dumb fouls in the final third.... Careless give-aways in midfield.... Defense switching off.... They seem clueless on set plays half the time.... And don't get me started on Gomes. Sure, he makes the occasional incredible save, but he makes some incredibly dumb decisions more times than not. Out of position, punching the ball out to the top of the 18 when he could easily catch it, etc. I can't imagine he gives his defense much confidence back there.
Not having Defoe or Lennon really hurt today. Not to mention missing Modric for this long. He was really the catalyst early in the season.
