Tommy Wright's Saints have made a fine start to the new campaign, collecting seven points from their opening three fixtures, and they are chalked up at a tempting 7/4 (2.75) to claim victory over the hosts here.
Jackie McNamara's side were expected to be challenging at the top end of the table this season but have failed to win any of their first three matches after being held to away draws against Partick Thistle and Hibernian, respectively, while the Terrors lost at home to Inverness Caledonian Thistle.
United are available at 13/10 (2.30) with William Hill to claim their first victory of the campaign thus far while the same firm go 21/10 (3.10) that the first Tayside derby of the season ends all square.
United have scored just one goal in three Scottish Premiership matches this season while the Saints drew a blank in their only domestic away match of the campaign so far.
It is also worth noting that Wright's men have kept three successive clean sheets in the league so a tight match looks likely when these sides go head-to-head on Saturday afternoon.
Should the match end 0-0, William Hill will refund all correct score and double result selections as a free bet – an offer which is sure to prove popular with punters.
Only two of the last 13 meetings between these sides has produced more than two goals so it is unsurprising that William Hill offer just 4/6 (1.67) that fewer than three goals are scored at Tannadice.
Both sides have scored in just two of the last seven clashes at Tannadice between the teams and defences may well be on top once again when they meet on Saturday afternoon.
Therefore, there is value in backing the in-form visitors at 19/20 (1.95) with William Hill in the draw no bet market here.
Those seeking to back bigger prices should take a chance on St Johnstone striker Stevie May to break the deadlock at Tannadice.
The 20-year-old, who has been heavily linked with a move to Peterborough United, has scored three goals in seven matches for the Saints so far this term and looks overpriced at a juicy 6/1 (7.0) with William Hill to open the scoring on Saturday.
