Paulo Bernardo has detailed conversations with former Celtic ace Jota about this time at the club.
The winger joined Saudi Arabian side Al-Ittihad for £25million during the summer transfer window after two successful seasons in Glasgow.
And Bernardo, who is on a season-long loan from Benfica, revealed both men are close.
He said: "I am working harder to make my impact. Jota has made his impact and I want to now make my impact.
"We are friends. I speak to him a lot of times, but now I have to make my own history here and hopefully, it's good, like him.
"He told me that the city was good, and I think that too. He told me about Celtic, that it was a really good and big club like we’re used to in Benfica, a really big club too.
"He told me that it's not too different, I think the thing that is different is the weather! I'm really enjoying Glasgow like Jota said I would."
Bernardo also opened up on the "boring" frustrations of the Portuguese league compared to the Scottish Premiership.
He has struggled for regular game time since joining Celtic on loan but a hamstring injury to Reo Hatate has meant the midfielder has featured heavily in the Parkhead side's last two fixtures against Atletico Madrid and Hibernian.
And the 21-year-old detailed what the main differences are between playing in Portugal and Scotland.
He said: "In football here, the game is more intense. The game never stops. In Portugal, we lost a little bit of time in the game because all the players go down to the floor so the referee stops the game.
"It's a little bit boring compared to being here. That's the thing I have noticed most that it is different."
