John Hartson beleives that Rangers forward Kenny Miller could trouble the Celtic defence if he is used as a central striker.

The 37-year-old continues to be an important member of Mark Warburton’s squad and has been used predominately in a wide position this season.

The experienced forward has still scored four goals and supplied four assists in 23 appearances, but summer signing Joe Garner has got the nod in the central position.

The Gers host Old Firm rivals Celtic on New Year’s Eve in the Scottish Premiership, but face games against Inverness and St Johnstone first.

Ex-Celtic forward Hartson claims that Miller would be the biggest threat to his former side and feels he would be more effective the Garner.

“Kenny Miller could give Erik Sviatchenko and Jozo Simunovic something to think about in the Old Firm game. Not Garner,” Hartson wrote in the Scottish Sun. “But for me, Rangers’ best chance is to play Miller through the middle against Celtic with Barrie Mackay and Martyn Waghorn on either side.”

Rangers will be looking for revenge against their bitter rivals on New Year’s, having lost the two previous meetings this season.

Warburton’s side suffered a humiliating 5-1 drubbing in the league meeting at Celtic Park and suffered a narrow 1-0 defeat in the League Cup semi-final.

Rangers’ result have improved since and they have won their last three games consecutively and have cemented their place as second in the league table, with runaway leaders Celtic 14 points above them.

Miller has experience of playing for both Glasgow sides and will be hoping to feature in the highly anticipated clash.

The Scotsman has racked up 216 appearances for Rangers, scoring 88 goals and supplying 49 assists.

The Gers must come through matches against Inverness and St Johnstone before their rivals as the busy festive schedule takes place.
