With two clean sheets apiece, the Manchester United and West Bromwich Albion defences have proved the most popular source of talent for Fantasy Premier League managers.
Four of the five top scoring FPL defenders are supplied by those two sides.
Gareth McAuley's (£4.7million) tenancy at the summit of the defender rankings has assured his popularity since the Gameweek 3 deadline.
The commanding centre-back has claimed more than 118,000 new owners and is now found in over 20% of squads.
That figure dwarfs team-mate Jonny Evans (£4.5m), who has been favoured by 7.7% of FPL managers.
For those who have ignored Ben Foster (£4.6m) as an option in goal, there is a clear case to consider one, or indeed both, of the Baggies defenders.
Tony Pulis' outfit look set to rely on defensive resilience to earn results and McAuley and Evans are major threats at set-pieces.
Jose Mourinho's United have also claimed two shut-outs and boast their own defensive options with attacking potential.
Luke Shaw (£5.6m) has so far proved their most popular target; found in more than 25% of squads, he has been brought in by over 77,000 managers this week alone.
However, in light of his withdrawal from England's squad with a calf problem, he ranks third in the transfers-out chart over the last 24 hours.
Shaw is nonetheless expected to be fit for the Manchester derby on Saturday. As is Antonio Valencia (£5.5m), despite a scheduled late return from international duty with Ecuador.
Valencia is owned by 11.8% of FPL managers but tops the ICT Index for both Creativity and Threat within the Red Devils' defensive ranks.
Like West Brom, if you have overlooked David de Gea (£5.5m) in goal, there is a strong argument to seek out one or even both of Mourinho's raiding full-backs.
Everton's Mason Holgate (£4.6m) has been a hugely popular target of late, attracting over 116,000 new owners so far ahead of Gameweek 4.
He has delivered outstanding value but seems set to come under threat from a fit-again Seamus Coleman (£5.4m) in the coming Gameweeks.
Everton's fixtures certainly make them worthy of investment: Ronald Koeman’s men record a score of only four on the Fixture Difficulty Ranking (FDR) for their next four outings.
A move for Ashley Williams (£5.0m) or the more expensive Leighton Baines (£5.5m) looks the current optimum route as we wait on the shake-up at right-back.
Elsewhere, the FDR advises considering both the Arsenal and West Ham United rearguards.
Hector Bellerin (£6.5m) has suffered a decline in ownership heading into Gameweek 4 but enjoys a run of matches that record only 11 on the FDR over the next seven Gameweeks.
As for the Hammers, James Collins (£4.6m) continues to figure on Slaven Bilic's teamsheet and boasts an FDR of 13 over the same spell.
