Meireles arrived in August from Porto.
He told liverpoolfc.tv: "I knew the English game before I came here and for me this is one of the best leagues in the world.
"I always wanted to play here and I'm really enjoying it at Liverpool.
"It's different to the Portuguese league. The pace of the game is faster and the action never stops.
"It is also more competitive but I like this and I'm looking forward to Sunday's game."
