How are chelsea bottlers nicole? where they have won considerable amount of trophies these last 6 years. Now Arsenal i do agree with.
Look at the league table now, before Ray Wilkins was sacked, Chelsea were 6-7 points clear of United.
And they've also bottled several important games (semi final vs United this year, final in moscow, games vs barca couple of years ago) it might be harsh to put them on the same level as arsenal, but they've threw away important points margins, semis etc by letting the pressure get to them.
Arsenal are ofc by far and away the biggest out of anyone however.
