Not a good video to watch, although it just seemed to be those around the mic we could hear at the point. I guess the away fans have spent hours and hours getting there, as well as good money and for those brief moments have a target for their anger when the players come over with the backroom staff. Not an excuse, but just can see how it is like a pressure relief valve.
Truth is, the captains arm band is weighing Son down, he should never have been made captain. Did we ever see anything in his character over the years to suggest he would make a leader, a battler, someone who would put his neck on the line when needed ? Whether the captaincy was given for commercial reasons or as a reward for loyalty doesn't really matter, if the cap doesn't fit there is no point.
I feel sorry for him, being overplayed and remaining on the pitch while others have been subbed off has been a pattern this Season. We can all see it, even more so at the games where you get to see more of his demeanour and fitness level, than the TV shows.
At this point if an offer did come in, I think it would be better for Son in himself to make a move. I just don't think all this negativity is good for him, he just isn't that person to absorb it, I feel.
