Grof, who has made just fourteen first team appearances this term, has fallen behind a succession of loaned-in stoppers.
Following a string of error strewn performances the Hungarian was first replaced by Nottingham Forest prospect Karl Darlow, then Wolverhampton Wanderers 'keeper Aaron McCarey followed by a returning Darlow and finally, after Darlow's surprise call up to the Forest first team Grof then fell behind Milton Keynes Dons' young goalkeeper Ian McLoughlin, who joined the club on an emergency 28-day loan deal.
It has been reported Walsall's goalkeeping coach Mick Kearns is firmly behind the signing of goalkeepers as he believed Grof has a lot to prove to return to the fold.
Smith told the Express and Star that David has shown fight but he must compete with the other goalkeepers to prove his worth to the team.
Many supporters see the influx of loaned in 'keepers as a slur on Grof and are fully behind the 23-year-old, who is assured of a positive reception, if and when he returns to the first team.
