Wing wizard Fabio Nunes spent almost a decade with the Portuguese club before signing for Rovers last summer.
Fabio first joined the Segunda Liga side at the age of seven and returned for a second spell after two years with Benfica.
He departed at 17 to join Porto and had a brief spell with Serie A side Parma, before arriving at Ewood Park.
The Portuguese playmaker is enjoying being back in his homeland and is looking forward to tonight's second pre-season friendly of the summer.
"I'm very happy to be in here in Portugal - my country - and even happier to be near my town, my family and my friends," said Fabio, who turns 21 later this month.
"I know everyone here. I know the pitch, the training ground, the hotel, everything here.
"It won't be an easy game, because they are used to being in the second league in Portugal.
"It will be a good test for Blackburn Rovers, because in Portugal there are some technical players, who know what to do with the ball, so it will be a hard game.
"I played here when I was young and I have good memories of that time."
Fabio endured a frustrating first season in English football, which was dogged by injury, but he hopes a full pre-season under his belt will stand him in good stead for the season ahead.
"I got many injuries last season, so I expect this season not to get so many and I hope to play more," Fabio added.
"Pre-season is very important to be able to play all of the season, so the most important thing is to work hard in pre-season."
Fabio made just seven appearances for Rovers last season, winning two man-of-the-match awards at Ewood Park, and he is delighted that the fans have appreciated his direct displays.
"Every game that I played, the fans supported me and I hope the fans will keep on supporting me this season," he added.
"It doesn't matter how I do personally - I just want to play as many games as possible and I want to see the club get promoted. That is more important than the amount of goals or assists I get.
"I'm enjoying being in England and I like everyone at Blackburn Rovers. I want to thank everyone for making me feel so welcome, from my first game.
"It was a shame that I got so many injuries, but now I hope not to get any injuries and to play more this season."
