The Saintsâ€™ mini-revival of four matches unbeaten was ended on the weekend as they lost 1-0 at Liverpool which saw them remain in the relegation zone.
"Weâ€™re making strides forward, thereâ€™s no doubt about that," Lallana told the Daily Echo.
"Christmas is going to be massive. We've got a huge game against Reading. Itâ€™s important we pick up points at home, especially against the teams around us, and weâ€™re focusing on that now.
"Weâ€™ll put this game to bed, and itâ€™s a huge game next weekend."
