South African defender Siboniso Gaxa is a target for Rangers, according to the player’s agent.

The right-back, currently contracted to Belgian club Lierse, is said to be in Ally McCoist’s sights if a deal for Estonian international Enar Jaagar fails to materialise.

A move for Jaager is said to depend on finance, with McCoist reportedly told to shift players off his wage bill before bringing anyone else in.

Gaxa’s agent, Rob Moore, says his client is next in line if a deal doesn’t come off for the Rangers trialist.

“Gaxa is seriously in the frame for that move,” Moore told Soccer Laduma. “If they don’t sign Jaager, then he is their next target.”

Gaxa has 48 caps for South Africa and featured for his country in all three of his nation’s matches at the 2010 World Cup.

His contract with Lierse runs until 2013, suggesting a fee would be payable to the Jupiler League side to take him to the Scottish Premier League.

The 27-year-old moved to Belgium from Mamelodi Sundowns shortly after the tournament, having also played for Supersport United in his homeland.
