Tottenham defender Vedran Corluka has joined Bayer Leverkusen on loan until the end of the season, the Premier League club have announced. The full-back was a regular last season but has dropped down the pecking order at White Hart Lane following the excellent form of England right-back Kyle Walker, who was on loan at Aston Villa last season. Corluka, who joined Spurs in 2008 from Manchester City, will spend the rest of the season on loan at the German club, who are currently sixth in the Bundesliga.
