The tactics weren't exactly the same against Chelsea and Stoke. My best guess would be:
vs Stoke
CDR-Ball Playing Defender-Defend (Skrtel)
CDC-Limited Defender-Cover (Kyrgiakos)
CDL-Ball Playing Defender-Defend (Agger)
MR-Wide Midfielder-Auto (Kelly)
CMR-Center Midfielder-Defend (Lucas)
CML-Center Midfielder-Auto (Aurelio)
ML-Wide Midfielder-Auto (Johnson)
AMR-Advanced Playmaker-Attack (Gerrard)
AML-Attacking Midfielder-Attack (Meireles)
CF-Complete Forward-Support (Kuyt)
vs Chelsea
CDR-Central Defender-Defend (Carragher)
CDC-Limited Defender-Defend (Sktrel)
CDL-Central Defender-Defend (Agger)
DM-Anchor Man-Defend (Lucas)
MR-Wide Midfielder-Auto (Kelly)
CMR-Advanced Playmaker-Attack (Gerrard)
CML-Center Midfielder-Auto (Maxi)
ML-Wide Midfielder-Auto (Johnson)
AMC-Attacking Midfielder-Attack (Meireles)
CF-Complete Forward-Support (Kelly)
