Pompey will look to maintain their position at the League One summit when they visit Coventry this weekend.
And Kenny Jackett’s side are the 11/8 favourites with Sky Bet to collect all three points at the Ricoh Arena.
The hosts – who sit 14th after winning promotion from the fourth tier last term – can be backed at 21/10, with the draw at 11/5.
Pompey drew 1-1 on their last league visit to Coventry back in 2012 and a repeat of that scenario carries odds of 5/1.
More optimistic punters might instead prefer to put their money on a 1-0 win at 13/2 or a 2-1 triumph at 9/1.
You can also take advantage of a Sky Bet boost, with the visitors coming out on top in a contest where both sides find the target moving from 4/1 to 5/1.
And those anticipating a comfortable evening might be tempted by the 18/1 on offer for the Blues netting four times or more.
Skipper Brett Pitman is the 5/1 favourite to net the opener, ahead of Ronan Curtis, Oli Hawkins and Jamal Lowe at 6/1.
Elsewhere in the first goalscorer market, Gareth Evans, Ben Close and Matt Clarke are available at 8/1, 18/1 and 28/1 respectively.
