Something needs to change for Tottenham Hotspur and there are plenty waiting for their chance.
Why was the defender bought if Tottenham don't plan on using him when their main back four are struggling?
This summer, the young but imposing centre-back arrived at White Hart Lane looking to make an impression. He was overshadowed by Toby Alderweireld, who came in as the bigger of the two signings and started alongside good friend Jan Vertonghen straight away.
But the north London side's defensive problems persist. And, of the two, it's Vertonghen that's looking the shakiest - far too complacent, as though he knows he will never be dropped. It's time to give Wimmer a go in his stead.
Why was the defender bought if Tottenham don't plan on using... oh right, that point has already been made!
It's exactly the same principle with the 24-year-old, who enjoyed a superb pre-season. His reward? In Mauricio Pochettino land, naturally that was the bench.
Kyle Walker is still defended by many but there are a number of calls for the right-back to be dropped at the moment. It needs to be done. Even if it isn't as a punishment for his own form but rather to stop talent like Trippier sitting on the bench doing nothing - especially when Spurs are clearly short of ideas going forward out wide.
Pochettino brought Alli on against Leicester and, to the manager's credit, the 19-year-old made an impact and scored for Tottenham.
But it's time to start him. There are teenagers who need protection, whose confidence could get knocked on the big stage. It's about assessing character, however: Alli is clearly not one of those teenagers.
Every challenge that has presented itself to him so far has seen him go unfazed. Real Madrid, Old Trafford and his real first chance to score a Premier League goal.
Alex Pritchard should also be considered to solve Spurs' problems out wide, although he is still getting back to fitness and is yet to feature for the first team. Alli has already made an impact for the north London side and can really help sort out their hole in central midfield.
