It seems the former Chelsea defender will be missed by the Spaniard at Stamford Bridge.
Cole could now end up playing against Chelsea in next season's Champions League, while also trying to prise the Italian title away from Juventus.
But the 33-year-old will not be forgotten in west London, with Torres posting a tribute to the defender on social media, wishing him all the best for the future and thanking him for teaching him 'so many things.'
"It's been a real pleasure to play alongside you [Ashley Cole]. You deserve the best of luck in your new adventure. Thanks to teach me [sic] so many things," he wrote on Instagram.
Torres scored just five times and registered five assists for the Blues in the Premier League last season, although the Spaniard's record was considerably better in Europe.
The striker also scored for Spain in the World Cup during their consolation 3-0 victory over Australia.
No real reports have surfaced over Torres' future this summer, suggesting he could be set to stay at Stamford Bridge next season.
The 30-year-old, then, could well end up playing against his old friend in Europe. That is, of course, if the Spaniard can win his place in a team that will also contain Diego Costa and possibly Romelu Lukaku and Demba Ba, whose futures are less certain.
