A This.
From 13 mins in is the thoughts of a local German football expert/journo (15 years covering Nuremberg) on how Singh is going. Anyone criticising Singh from thousands of miles away should watch that segment at least.
In summary Liga 2 is a tough physical league, and that part of his game needs to improve, but is some signs that it is. Patience required, and as quickly as some fans are not happy now, in short time they could easily be adoring him, fickle beasts that they are.
Nobody here's really criticising Singh - it's okay to be honest if a spell isn't working out and it'd be a little disingenuous to only cover the good and leave out the bad. Better to know than ignore. Just can't wait for him to regain his confidence. I know that there's many teams who will properly utilise and appreciate his skillset out there
