Just checked the source for the wiki article, that is correct, unless all of the stats sites are wrong and have decided to arbitrarily claim Lallana's scored more goals than we think:

One goal each away at Wolves...
He scored one goal in all competitions in his last 3 seasons with Liverpool.
From a quick look on Wikipedia, seems to have dropped off a cliff around the same time his appearances started declining, so maybe linked to injury problems, position played, confidence etc.
Last season was his best...
