Corluka joined Lokomotiv from Tottenham Hotspur last June on a three-year deal that reunited him with former Croatia boss Slaven Bilic.
Fresh reports have suggested that he could be set to return to the Premier League, perhaps with West Bromwich Albion or Everton, and his representative is not surprised by the interest.
Niki Vuksan says his client would be a useful addition for any team, but he is not sure what will happen in the summer.
"There is nothing strange in the fact that a number of European clubs are interested in my client," he told Izvestia.
"Corluka is a very talented player and his advantage is that he is also a very universal player, he can play in many positions.
"But I don't want to talk a lot about his future. He has a long-term contract with Lokomotiv Moscow and these things are difficult to predict.
"Let's wait until the end of the season, when everything will become much clearer."
