Lallana is a very good squad player, no doubts about that. But when you spend £23m on a player, I expect him to be starting and I look to him to make a difference. Even the manager didn't have faith in him to take him off the bench today.
This could say much more about the manager than the player! Lallana is in a new team and like any other player will take time to settle, how many full games has he played for you?
