Tsimikas begun his post on Instagram by quoting Jota's famous Liverpool chant: "Oh he wears the number 20 and his name is Diogo."
He continued: "We’ve moved to the club the same period. We were the new boys in the city. We’ve shared and celebrated some of our best moments of our careers together. Before one of our last ones you’ve said to me 'You cross, I score' and that’s what happened. We laughed and we talked about lots.
"You were a special player, a special guy, a true legend Diogo. You’ll always be remembered and always be loved. My heart and my prayers are with your Rute, your boys, your little girl, your family and everyone who loved and waited for you both to go home. You and your brother André will be missed forever."
Tsimikas then had some powerful words in Greek: "Good paradise Diogo and Andre. May God give strength to your loved ones to endure the nightmare and may they one day see the light again," he said.
"We love you Diogo. YNWA."
