Salah and Coutinho were together on Merseyside for just half a season after the Egyptian joined the Reds from Roma last summer. But in that time they grew close, both on and off the pitch.
Asked by Marca if he misses Coutinho, Salah replied: "I miss him anyway! He was my friend, a very nice guy. I wish him all the best in Barcelona because he is an incredible player, with a lot of quality. As a person he's very calm. I'm proud to have played by his side."
The Egyptian hero has netted 21 Premier League goals and has ambitions of taking home the Golden Boot ahead of Harry Kane at the end of the season. He is also in contention for the continent-wide European Golden Shoe alongside Lionel Messi and Edinson Cavani.
But rather than embrace any speculation about Real, Salah is keen to quash it.
"I don't have much to say about that. If I have to say something, I'll say I'm happy at Liverpool," he said.
Salah and Liverpool will be back in action when the Reds travel to the south coast to take on relegation threatened Southampton at St Mary's. The game will also mark a first return to his former club for ex-Saints defender Virgil van Dijk.
