We always seem to concede cheap corners at set pieces and/or from crosses. Happened last year as well. I do think that perhaps its not too far away from being the right time to change a centre back. I thought Boxall and Rodriguez both had very good games. Boxall could easily replace Dura/Sigg at Cb given some time. Much stronger in the air and keeps his head down (Doesn't continuously complain to the referee)
Krishna needs to regain sharpness. Too often the first touch wouldn't be good enough and the move would stall. Still stand behind my thoughts that Boyd is the better footballer.
Oh and to the guy who sat behind us today who kept going on about how sharke Rodriguez is and how Lia should have been brought on for him: You have no idea what you're talking about.
