Zenit St Petersburg have signed Portugal defender Bruno Alves from Porto for a fee of €22 million, as they look to cement their position at the top of the Russian Premier League.
Alves, 28, won four league titles and three domestic cups during a five-year spell with Porto, but has now moved on to pastures new, joining nternational team-mates Danny and Fernando Meira at the Petrovsky Stadium.
Zenit are unbeaten in 15 games this season and sit nine points clear of second-place CSKA Moscow, with the signing of Alves likely to help strengthen the 2008 UEFA Cup winners' position atop the table.
Alves is Zenit's third signing in recent weeks, following the arrival of striker Aleksandr Bukharov from Rubin Kazan and defender Aleksandar Lukovic from Udinese.
Luciano Spalletti's side recently claimed a Russian Cup triumph and host Unirea Urziceni in the second leg of their UEFA Champions League third qualifying round tie on Wednesday night with the scores level at 0-0.
