Newcastle United defender Davide Santon is "fully focused" at the club, but could leave in the near future.

The 23-year-old, who was initially left out of the Toon squad following a 4-0 defeat against Tottenham Hotspur last month, has been a reported target for Russian club Zenit St Petersburg.

"We have several times had a conversation with the Russian team which has taken an active interest in my client," the player's agent, Renzo Contratto, is quoted as saying by the Northern Echo. "It must be understood that many European teams are interested in my client.

"Now the player is fully focused on performance for his club, but no one knows what will happen in the summer. I do know that Newcastle are not going to release the player for less than a certain amount."

Santon joined the Premier League side in 2011.
