Football fans will often take inspiration from one another, and Manchester United supporters are not above such an approach.
Supporters were seen debuting a new chant in honour of latest signing Casemiro. The Brazilian international has joined from Real Madrid in a deal worth a reported £60m, but was named among the substitutes for the Premier League game at Southampton after arriving too late to feature against Liverpool on Monday.
The tune was a familiar one, too. Certainly, Arsenal fans will have recognised the tune, having delivered a similar chant for two of their own players last season which sounds awfully similar.
