Having impressed for Uruguay at the World Cup in Russia, Torreira left Samp to join Arsenal in July 2018, becoming Unai Emery's most expensive signing at a reported fee of close to £27million.
The 23-year-old had a promising debut campaign at Emirates Stadium, making 50 appearances in all competitions and scoring three goals as Arsenal claimed a fifth-place Premier League finish and reach the Europa League final.
However, Torreira has revealed that, despite his performances on the pitch, he has endured a hard time adapting to England, conceding he preferred his lifestyle in Italy.
"I don't know if there are many things that I enjoy," Torreira, who is part of Uruguay's squad for the upcoming Copa America, told Uruguayan outlet Ovacion.
"The language [barrier] has stopped me being able to relate with my team-mates and with the people. It is very difficult when you can't have dialogue.
"And so is the climate. You go out in the morning and it is cloudy; you arrive late to your home and it is cloudy.
"It is strange a little bit, we are accustomed to always having the sun, or almost always. But as the years pass, I'm going to be adapting."
Torreira signed a five-year deal with Arsenal, though reports in Italy have suggested he is a target for AC Milan, who look set to announce Marco Giampaolo - who coached the player at Sampdoria - as their new boss.
Arsenal start the 2019-2020 league season away at Newcastle United on August 11 and face Burnley at home before taking on last season's runners-up Liverpool and arch-rivals Tottenham in late August.
