Opta Stats: Aston Villa and Southampton to keep it tight

Diego Costa hasn't scored in seven games for Chelsea

These Opta insights hint at Crystal Palace wobbling, West Ham netting at Arsenal, Sunderland being hushed and a low score at Stamford Bridge...

Crystal Palace v QPR (Saturday, 12:45, BT Sport 1)

QPR are unbeaten in the last seven league meetings with Crystal Palace (W3 D4 L0)

Whereas Crystal Palace have won a rather special five of their six away matches under Alan Pardew, with the sole setback an excusable 1-0 loss at Southampton, they are winless in four at Selhurst Park, suffering three defeats. Their bogey club QPR are finally over their crippling travel sickness, winning at Sunderland then holding Hull until the 89th minute despite playing almost an hour with ten men.

Recommended Bet: Lay Crystal Palace to win @ 1.834/5

Arsenal v West Ham (Saturday, 15:00)

The Hammers scored the first goal in four of the last five Premier League meetings with Arsenal

While the impressiveness of that stat is compromised by West Ham going on to lose every single one of those games, the pattern fits their form neatly. The Irons have outplayed Man United, Tottenham and Chelsea across their past five league outings without prevailing against any of them. They broke the deadlock against the Red Devils and Spurs, much as they did on their previous two Emirates trips.

Recommended Bet: Back West Ham to score the next goal @ 3.7511/4

Sunderland v Aston Villa (Saturday, 15:00)

Sunderland have failed to score in five of their last six Premier League matches against the Villans

January's Jermain Defoe for Jozy Altidore swap has yet to prove the genius deal that many initially interpreted Sunderland to have conducted. The veteran poacher has notched twice in nine starts - a tally his predecessor recently equalled on his Toronto debut. The Black Cats as a unit have struck just once in five games, and only three teams have kept more away league clean sheets than Aston Villa.

Recommended Bet: Back Aston Villa to keep a clean sheet @ 3.39/4

Chelsea v Southampton (Sunday, 13:30, Sky Sports 1)

Chelsea have scored only once in each of their last three home league matches

The Premier League's two best defences meet in this fixture having conceded a combined 42 goals in 55 encounters, and all of the evidence points to under 2.5 goals. Their St Mary's skirmish delivered a mere two shots on target, Chelsea have leaked three times in their last 11 home league clashes and Southampton seven in 11 on the road. Much as the bold trend above reveals the hosts' diminishing attacking potency, the Saints have scored just twice in six league games.

Recommended Bet: Back under 2.5 goals @ 1.834/5
