Ex-boss admits he regrets leaving Chelsea after just one season.
The Italian coach expressed his desire to leave Stamford Bridge in 2019 and join Juventus instead.
He guided the Blues to success in the Europa League in just one season at Stamford Bridge.
He however regrets for forcing his move to Italy even though Marina Granovskaia, the Chelsea director, wanted him to stay.
Speaking to AlfredoPedulla.com, Sarri said: ‘At Chelsea, I made a huge mistake and that was wanting to return to Italy at all costs.
‘Marina tried stopping me from leaving Chelsea, I had this desire to return to Italy.
‘Chelsea are a great club, in the following years [after I left] they have signed many young players suitable for me.
‘I lived a particular year, in which Abramovich could not enter England and we had an owner not present in the stadium.
‘A rather difficult situation, all in the hands of Marina and she had a thousand problems to solve, the football aspect was in the hands of staff, not having the economic power available.
‘Then came Werner, Havertz, Mount, Ziyech – all suited to me and my way of playing.’
