Mane is proud of his achievements at Saints.
He told Sky Sports: "I think there is a big difference because Liverpool is a big team of course, but I also had two great seasons with Southampton with nice people and we had a good manager like Ronald Koeman.
"We were successful because we went into Europe. I'm not there anymore, but I'm happy to be at Liverpool. Everything is going well for us at the moment and I think it will continue."
