Dele Alli admits he was "very upset" by Mauricio Pochettino's departure from Tottenham and initially felt to blame after the Argentine was sacked, reports Sky Sports.
"When it first happened, you just blame yourself when you're sad and you don't really look at the big picture," said Alli, ahead of Tuesday's Champions League match against Olympiakos.
"We've had some amazing journeys together, we grew together - all the coaching staff that were here and the players, we all grew. We achieved a lot in terms of where we came from. We're all very thankful to him.
"You can't help but feel a bit to blame because we were out there but when I look back I gave 110 per cent and so did all the players.
"Sometimes it just doesn't work out. The chairman made a decision and, like I say, we owe [Pochettino] a lot of thanks."
Alli has confirmed he also visited the Argentine the day after his departure from Tottenham.
"It's clear to everyone how much Poch meant to the players," added Alli. "I've been here for nearly five years now, he's seen me grow a lot as a person and he's helped me a lot.
"I came here as an 18-year-old, new to it all, and I've been through a lot of ups and downs here and he's helped me through of all of them, so I can't thank him enough.
"I think it was important. Straight away, as soon as I found out the news, obviously I was very upset but I tried to get in contact with him and the next day I went to see him."
