Chelsea scout Piet de Visser says he was left in "shock" after witnessing one of former Blues boss Luiz Felipe Scolari's training sessions.

De Visser warned Roman Abramovich to act when Chelsea were on the slide under Scolari.

De Visser said: "I had to watch training sessions he was giving to the squad. I died of shock.

"It was so weak, his training sessions lacked every kind of sharpness.

"It made the entire squad lack sharpness in matches. I did not need a lot of time to conclude things were really bad with Chelsea."
