Ross County have signed former Liverpool striker David Ngog until the end of the season.

The 28-year-old arrives in Dingwall as a free agent after recently leaving Greek Superleague side Panionios.

Staggies boss Owen Coyle spent £4m on the Frenchman in 2011, signing him for Bolton from Liverpool.

"I am all too familiar with his qualities and I think he will be an excellent addition to our attacking options," Coyle told the club website.
