(Reuters) - American Zach Johnson has arguably been the hottest player in the game over the past five months and his decision to take the next four weeks off raises questions over whether he can regain his sparkling form on return.

Johnson himself has no doubts and said on Sunday he is already thinking of ways he can improve the quality of his golf before making his competitive comeback at the WGC-Accenture Match Play Championship in Tucson, Arizona.
