Jari-Matti Latvala is on the brink of clinching Rally GB victory, but Ford no longer holds a one-two as Sebastien Loeb has moved into second.
Having struggled to match the Fords so far this weekend, Loeb raised his pace on Sunday morning and quickly caught Petter Solberg for second.
But the Citroen driver remains concerned that Solberg will be faster during the decisive three afternoon stages, which they will start just 2.9 seconds apart.
Latvala is under no pressure, though. His lead stands at 29.3s and he even took another stage win on Walters Arena.
It was a tough morning for the Ford privateer pack. Mads Ostberg and Matthew Wilson both developed time-consuming misfires. While they held on to their respective fourth and ninth positions, it meant the end of Ostberg's faint hope of catching the podium fight.
Mikko Hirvonen was much happier with his Citroen on Sunday morning and has closed to within 23s of Ostberg.
The Finn is also no longer under pressure from behind, as M-Sport Ford's Ott Tanak and Evgeny Novikov both lost time with trips off the road on Port Talbot.
