The Colombian played for Al Rayyan for one year after leaving Everton in 2021 but made just 13 appearances as he could not settle.
Despite signing a three-year contract worth £6million a year, this was terminated in September last year and he signed for Olympiacos.
And the attacking midfielder has since revealed he could not settle in Qatar due to their customs, including not being naked while showering after a match.

"Everyone there eats with their hands, which was difficult for me.

While he won two Bundesliga titles, the 2014 World Cup superstar did not enjoy his time in Munich and even described the people as cold.
"It's cold there. The Germans are also cold people, even if I was treated fantastically at FC Bayern," he is quoted as saying.
"There were days when I went to work at 9am, I turned on the car and the temperature was -28.
"I say: 'What am I doing here? Munich is a city that has a lot of quality of life, but I couldn't be comfortable."
Rodriguez has since left Europe and signed for Brazilian side Sao Paulo, joining in July where he has signed a two-year contract.
Across a nomadic career, he joined Everton in 2020 to reunite with Carlo Ancelotti but fell out of favour when Rafa Benitez joined.
