BOL - thats a VERY limited / bias view
Look at where Chelsea are in the league , Cech may not be the main failure this season, but he hasnt been at his best either (just like Reina, who until this season I thought was clearly the best keeper in the league, and has been for a number of years)
edit - after reading Tom's second (I think) post stressing "overall" rather than just this season, its impossible to say as some like De Gea have changed leagues (and therefore cant be commented on for vast majorities of posters, who might not have seen him previously), a lot of other g/k may not have played internationals / Euro matches so only have league form to go on, and Cech / Riena have had terrible years compared to their usual high standards
For right or wrong, I still dont think Cech should be allowed to wear the skull cap indefinitely. If he is physically fit enough to be in goal, he shouldnt have any advantage over any other g/k - and if he isnt fit enough, he shouldnt be there in the first place ( while he was recovering from the initial injury,thats one thing......but as an additional piece of kit indefinitely, definitely not)
