Brady is Arsenal's youth academy director

Brady also believes Blues boss Jose Mourinho has riled some of his players.

"There could be trouble. How is Arjen Robben going to feel if he is not included in the plans," said Arsenal's youth academy director.

"I'm hoping they lose a couple of games and there's a crisis because they've upset a lot of people over the last three years, Mourinho in particular."

Brady's slating comes on the back of the long-running Ashley Cole saga that caused a rift between the two teams.

Cole, who was fined by the Premier League after he was found guilty for having a secret meeting with Chelsea, has been critical of former team Arsenal in his autobiography.

Cole finally joined the Blues during August's transfer window with Chelsea defender William Gallas going the other way after also criticising the Stamford Bridge club.
