Newcastle United and Manchester City are chasing Deportivo La Coruna defender Fabricio Coloccini.
The 26-year-old is valued at 13 million Euros and Lotina knows, given Deportivo's financial constraints, that without the sale his ability to strengthen would be limited.
Spanish clubs - thought to include Real Madrid and Barcelona - are also interested but Coloccini's agent, Marcelo Lombilla confirmed talks with the English clubs are more advanced.
He told AS: "There are two important teams willing to pay a very good amount. The two clubs are very serious in their interest. If not, I would not be going backwards and forwards to England.
"There are teams in Spain that are also interested, but one must be slightly patient."
