Vote: Are Aguero, Alli, El Shaarawy, Kurzawa, Proto the UCL stars?

Another round of UEFA Champions League fixtures has come and gone, leaving us with a number of memorable performances during the fourth week of the group stage.

There's no denying that Tottenham Hotspur made a statement with a 3-0 victory against Real Madrid at Wembley Stadium that left them top of Group H. Sergio Aguero also celebrated when he set a Manchester City club record with his added-time goal against Napoli.

But there were some curious results, too, such as Atletico Madrid's draw against Qarabag and Borussia Dortmund again failing to defeat Apoel Nicosia.
