The Argentine was let go six months after he led the club to the Champions League final and after more than five years in charge. Spurs appointed former Manchester United manager Jose Mourinho as his replacement on Wednesday.

"Big thanks to you all," Pochettino wrote. "We can't say goodbye you will always be in our hearts."
Spurs players also posted messages on Twitter, thanking Pochettino for shaping their careers.
"I'll be forever thankful to you for helping me achieve my dreams," striker Harry Kane wrote.
Teammate Dele Alli tweeted: "He's taught me so much and I'm so grateful for everything he's done for me. Good luck and hope to see you again my friend."
