Tottenham have completed the signing of Romania defender Vlad Chiriches from Steaua Bucharest.
The departures of William Gallas and Steven Caulker left Tottenham short on numbers at the back, but they have now resolved the problem by signing 23-year-old Chiriches for a fee of around £8.5m.
"We're delighted to announce we have reached agreement with FC Steaua Bucharest for the transfer of Vlad Chiriches," Spurs announced on Twitter.
Chiriches played 62 times for Steaua during a two-year period at the club and he has made 19 appearances for his country. The defender is Tottenham's fifth signing of a busy summer which has seen the north London club spend £67m in the market.
"For me, this is something incredible. A dream come true," he said.
Chiriches will compete with Jan Vertonghen, Younes Kaboul and captain Michael Dawson for a place in the heart of the Spurs defence. Villas-Boas spoke fondly of the centre-back on Thursday night following Spurs' 3-0 win over Dinamo Tbilisi in the UEFA Europa League.
"He is an interesting player that has been followed by lots of teams," Villas-Boas said. "He has tremendous qualities coming out with the ball and that's what we like in our defenders. He is a great leader."
