I happen to agree our defending was shown up in the second half against Spurs, but disagree our defenders were much to blame on this occasion. They are four players, and most of Spurs chances came as a result of them overplaying our midfield and outnumbering our defenders at speed, or getting easily to good crossing positions with lots of players in the box, leading to a few chaotic situations.
I think both Lindelöf and Jones did a very good job under extremely difficult conditions, particularly the last 30 mins. Not perfect, but very good.
Against top opposition, we need to defend better as a team for 90 mins, though.
