Been reading the thread over the last few days and thought I would chip in with my thoughts.
1) Rubén is undoubtedly an extremely talented lad, probably the best we have seen for some time physically and technically.
2) I thought defensively against Liverpool he showed a lot f maturity but did get caught out at times which is of course natural.
3) having been on nights Weds I watched the entire game and thought he did ok. People saying he was lazy I would challenge who didn't? Allegedly we had a double session prior, the GK (least physical pos on pitch ) was struggling. Rubén played in the no10 role that game and as such didn't have as much responsibility defensively, however I agree he didn't press nearly as high as I would have liked
To sumarise this is an exceptional talent who will only get better. I believe that he gets caught out mainly due to lack of concentration , this level is a million miles away from YTS and so are the players. This concentration level will improve with consistent games against top opposition. Finally to whoever compared him with Mido, Mutu and Babayaro, I will have what you're drinking
