Portsmouth have not lost to West Ham United in any of their six previous Barclays Premier League meetings and have won all three of the meetings at the Boleyn Ground, including a 1-0 victory in April.
Quite how Gianfranco Zola's side lost 3-1 to Everton on Saturday remains something of a mystery. It was the ultimate smash and grab, with the home side dominating until the last seven minutes. West Ham UInited are 29/20 to beat Tony Adams' side, who earned a last-gasp 2-1 victory at Sunderland last weekend.
Portsmouth are priced at 37/20 to win their third away game of the season, while the draw, which has occurred twice in six meetings between the teams is 23/10. The away side can be backed to score at any time at 3/10, while it is 19/10 for West Ham United to keep a clean sheet.
JAXX offer odds on the first and last goal to be scored in every game. It is 6/5 that the last goal will be scored between the 76th and 90th minutes and 5/2 that it will arrive in the 61st to 75th minutes.
Only twice in the last six meetings between the pair has the match produced more than two goals in total. The odds on there being more than 2.5 goals scored in Saturday's clash are 17/20, while it is 3/4 that there will be fewer than 2.5 goals scored in the game.
Portsmouth can be backed with a mythical goal head-start at 9/20 on the Handicap market - West Ham United are 18/5 to win by two clear goals or more. A home win by the odd goal (a Draw on the handicap) is on offer at 53/20.
The half-time result can also be backed with JAXX. West Ham United have been in front at the interval in four of their 12 Premier League games so far and they can be backed at 61/20 to be in front at the break and at full-time. West Ham United are 37/20 to win the first half, whereas Portsmouth have been in front just three times at the interval in their 12 league games thus far and are 21/10 to go in at half-time with the lead. It is 1/1 that the game will be all-square at the break.
Portsmouth have not been particularly quick starters in their league games, having scored the first goal of the game in just a third of their games this season. It is 17/20 that Pompey strike first on Saturday, while the home side are the same price to open the scoring. It is 13/2 that there will not be a goal, but JAXX offer 7/10 that both teams find the net.
