Parker, Gayle or Howe offer more movement than Whitehall.
None of them have ever scored 20 goals in a season at National League level or as yet looked like doing it.
Whitehall has done it multiple times so when fit he will be and must be first choice.
However, according to an earlier post he has just gone a almost a third of a season without scoring at all in a fairly successful team. The clock is ticking. I would think he has half a dozen games to give some compelling evidence you he is still a 20 goal a season man. Without that he offers very little to the team in a key role given his lack of pace, movement and inability to hold up the ball.
