Former Celtic target Lafferty joins Derby's Miller back on Rangers' radar

Days after the Light Blues captured the Scottish Cup with a 3-2 win over Queen of the South at Hampden, manager Walter Smith began his search for new players to freshen up the Ibrox squad - but the Northern Ireland international is already on his radar.

The Govan club, who were linked with Lafferty during the January transfer window, failed with an undisclosed bid three weeks ago.

Wanted: Burnley's Northern Ireland international Kyle Lafferty

However, Smith could return with an improved offer for the highly-coveted 20-year-old.

Lafferty, contracted to Burnley until 2010, stands six foot four inches tall and can play as a conventional target man as well as wide on the left.

Celtic offered the Lancashire side £2.5million plus fringe player Derek Riordan in January, a year after a bid of £500,000 was rejected, but that was also knocked back.

Fulham had a bigger offer of £4million rejected last August when Lawrie Sanchez, who capped Lafferty for Northern Ireland, was boss of the London club.

Burnley will be looking for at least that figure if they are to lose the striker to the Clydesdale Bank Premier League.

Smith is also rumoured to be chasing Derby striker Kenny Miller, who played for Rangers before joining Celtic.
