Not as little as he has over the last few years, most number 2 keepers at least play regular cup games. Quick look and I think Karius has played 7 games in 3 years, would be a concern relying on him for any length of time if Pope got injured.
Not sure ASM would be happy solely being a bench player mind. If we are also relying on Joelinton being our main wide left player then we are another body short in CM.
