He would fit ernies system if burns/boyd goes. Hasnt played a lot recently though
True that he struggled with getting a chance to play, but that has also been the case with Burns.
Appiah simply ticks a couple of boxes - does not take up a visa spot, is available, will not demand an expensive deal, and to my best knowledge is not presently pursued by Shanghai Shenhua.
Contracting him (if it comes to that) sounds like an insurance policy in case we develop a dire need for another striker.
