I agree he was isolated but also he needs to do something about it - there was a flash of what i'd describe as presence before he came off when he really competed for a ball that wasnt his, which he didnt really show for 60 minutes prior. a bit timid i think. maybe harsh with the 10 men comment, he plugs gaps but doesn't really impact the oppositions play in defence (yet).
For me, Bobby came on, showed the presence, and made all the runs that minamino didn't, and it made a big impact on the team performance. minamino looked overwhelmed in comparison. To be clear I'm not writing him off, just that i see a big gap between the level he has shown in his first couple of games and the level he needs to display to play for liverpool. Must be really hard not speaking the language, without knowing any of your colleagues, and being expected to do your job; I certainly wouldnt be able to do it in my line of work so its not a criticism of him as a person, but an observation of his games so far.
