COMMENT By Harvey Byrne

The Scottish Sun reported earlier this month that Martyn Waghorn was looking to leave Rangers in January after becoming unhappy about not being offered a new contract.

Football Insider has identified three possible striker replacements for the 26-year-old:

Scott Hogan (Brentford)

The 24-year-old was brought to the London outfit by Warburton in the summer of 2014 from Rochdale for a fee of £750,000.

His contract is up next summer and he could be picked up for a relatively low cost in January, as Brentford will be keen not to see their star forward depart on a free transfer.

With 10 goals in 18 appearances in all competitions this season he will be sure to have many suitors, but with a possible reunion with Warburton and playing for a historic club like Rangers the Scottish side may win his signature.

Ross McCormack (Aston Villa)

A £12million summer signing, the 30-year-old has struggled to establish himself at the famous Midlands side.

McCormack is originally from Glasgow and even started off at Rangers as a youngster before moving to Motherwell in 2006.

At the late stages of his career he may be eager to move back home, but he could become useful for Villa in January with attacking trio Jonathan Kodjia, Albert Adomah and Jordan Ayew leaving for the African Cup of Nations.

Will Grigg (Wigan)

The Ibrox side were made favourites to sign the 25-year-old in the summer window and Rangers may look to strike a deal in January if Waghorn leaves.

Grigg will have been unhappy with the Latics’ poor start to the campaign, as the Lancashire outfit sit second from bottom despite his six goals from 17 fixtures.

The Northern Ireland international is now well known for the famous song and his name could be echoed around Ibrox in the future.
