Queens Park Rangers manager Harry Redknapp will reportedly revive the club's interest in Ajax forward Kolbeinn Sigthorsson as he looks to add firepower to the Premier League new boys.

According to the Daily Mail, the Dutch champions are holding out for £6m for the signature of the Icelandic international, who was a target of the West London outfit during the January transfer window.

Redknapp may be keen to bolster his forward line with both Bobby Zamora and Andy Johnson out of contract this summer, and Loic Remy has heavily linked with a move away from Rangers.

However, the R's may face competition from Celtic, Liverpool and Newcastle United, all of whom have watched the 24-year-old in action.

Sigthorsson has scored 15 goals in 23 international games for Iceland.
