Watching Alejandro Garnacho walk on to the field at Wembley with four minutes to go in the FA Cup Final told us much about Chelsea. Garnacho cost £40million from Manchester United. They thought it was a coup and‚ as so often is the case at Stamford Bridge‚ they were wrong. Four minutes to save a cup final. That kind of sums it up. If temporary coach Calum McFarlane really believed Garnacho had it in him to write Chelsea's name on the trophy‚ he may just have given him a little longer than that. As for Garnacho himself‚ he is still only 21. So we must be careful. Older and wiser and better players than he have been spat out of the Chelsea threshing machine. None of this is his fault.
