Zenit St Petersburg coach Andre Villas-Boas has taken a swipe at Roberto di Matteo.

Speaking with Expresso, AVB feels that he was betrayed by his players during his time with Chelsea.

The Portuguese also stated that he felt particularly let down by Di Matteo.

Unlike most of the rest of the coaching staff, the Swiss-born ex-Italy international didn't leave but accepted the job as Chelsea boss, when Villas-Boas had chosen him as assistant manager "against the will" of the club's higher ups.

Di Matteo managed to win the Champions League with Chelsea after succeeding AVB.
