Thiago Alcantara was left in tears before leaving for Liverpool, according to Bayern Munich CEO Karl-Heinz Rummenigge.
Thiago, 29, enjoyed a record-breaking debut after just 45-minutes on the pitch for Jurgen Klopp's side as they eased past Premier League rivals Chelsea on Sunday.
In what has been dubbed as one of the greatest bargains, with the Reds stumping up £5-million upfront with the rest of the fee set to reach £25m, due to the Spain international having one year left on his contract.
After winning seven consecutive league titles over season seasons at Bayern, he bid an emotional goodbye in order to take the next step of his career in England, which Rummenigge admits was far from easy.
"Regarding Thiago, I would like perhaps to add this story," he told Sky Germany, as per The Express. "So on Thursday the transfer, which Hasan [Salihamidzic] agreed with the people in Liverpool, has been granted.
"When I arrived, I would say, 10 minutes later in the parking garage, I brought my car, he was standing at the spot where I always park.
"I thought to myself, what's he doing here? 'Thiago' I said. He came up to me and cried in my arms for five minutes. [He] cried for five minutes and said simply, 'thank you very much for allowing this'.

"This is a great human being and was always a first-class player for Bayern Munchen and I was tremendously happy for him in Lisbon because he's always been questioned because he supposedly in the big games isn't capable of bringing the big performance.
"And now I think in Lisbon the entire three-game tournament he proved what quality he has. That he's now leaving us is a big loss, quality-wise on the pitch, but just also as a human being. And despite that, we respected that he wanted to do something new."
