He worked hard but all the things I listed in that post I stand by. I recorded and watched the Sky coverage, Souness and Neville also pointed out his problems and they weren't solely down to being up against Hazard. Did you not notice how Chelsea were targeting Yoshida rather than a 19 year old on the other side of the pitch? They saw Yoshida as the weaklink, I don't dismiss his efforts and workrate as he certainly put a shift in but he is a very limited player even when he plays in his normal position of centre back.
He would be okay if we were still a bottom half Premier League team, but he is far too limited technically to play for a team challenging as we are at the top of the league. Work rate simply isn't enough at the level Saints are aspiring to reach. I think Gardos looks more composure and assured on the ball, Yoshida panics with the ball at his feet and his distribution is poor.
