Thomas Tuchel was sacked by Chelsea earlier this month.
The German coach was replaced by Graham Potter as the new Chelsea manager this month.
Tuchel won the Champions League, Super Cup and Club World Cup in his short spell at Stamford Bridge.
But he failed to win over Christian Pulisic who has aimed a furious rant at his former manager in his new book.
‘What happened before that [second leg] was hugely disappointing for me,’ Pulisic said.
‘l’d had a really good first leg performance and our following match was against Fulham in the league.
‘Tuchel told me that he was resting me for the second leg and as a result I didn’t play a single minute in the Fulham game.
‘Then on match day… Tuchel tells me he’s changed his mind and he’s going with Kai [Havertz].
‘I honestly was dumbfounded and very disappointed. I thought that I’d earned a start and, most importantly, he had assured me previously I was going to start.
‘So by the time he brought me on with about 25 minutes left, I was just so wound up.’
