Five changes after a superb 3-1 victory, including dropping to the bench an on fire Vydra; stupid or what? Zola has been quick to point out that he pulled a similar stunt ahead of the Leeds game but he seems to have forgotten that those changes followed a 0-0 draw. He also doesn't mention that Leeds were down to 9 men in that game!
The result suggests Zola made a bad mistake. It's a cliche, but you don't change a winning side unless you are forced to. And as a result of this defeat, Watford have been reeled in by Millwall, Leeds, and a clutch of teams just beneath them. Charlton at home should yield three points to any serious promotion contenders, so all the good work achieved at Brighton has been tossed away needlessly.
Zola is still learning his trade so will make mistakes. The danger is that he will make too many.
