England hero Chris Waddle has questioned Maurizio Sarri's work at Chelsea.
Waddle thinks Sarri should be doing far better with the talent at his disposal.
"With this squad, Chelsea are severely underachieving," he told BBC Radio 5 live.
"They have so much quality on paper that they should be challenging Man City and Liverpool for the title."
Chelsea still have a chance to attain Champions League football even if they finish fifth or sixth in the Premier League.
