Onana can't be that bad considering Inter got to the CL final? But he's definitely having a bad time and it's entirely possible it continues and doesn't work out at Man Utd.
Spuds have had one of the kindest starts you could hope for. Played all 3 promoted teams plus Man Utd
Played Liverpool with 9 for a good chunk. Arsenal is probably their only 'tough' match so far.
