Alderweireld is a huge miss

When Toby Alderweireld limped off the pitch in Tottenham’s last Champions League outing – the impressive 3-1 win over Real Madrid – there would have been serious concern from the Spurs faithful.

Tuesday proved why they were so worried about their chances.

Without the Belgian, the defence lacks the composure he brings, although that is not to say that Jan Vertonghen, Davinson Sanchez and Eric Dier are bad at the back.

Still, Mauricio Pochettino will be hoping that his injury layoff does not last much longer, and that he can rejoin the partnership at the heart of defence.
