Agree, you'd also think that with Lambert playing he would be a good choice as those two have a history of linking up well and Sterling has looked tired.Yes, it's odd as he was their most expensive signing and he also seems like the most 'Rodgers' type player sort of like a younger better Leon Osman or Steven Pienaar. Not particularly pacy but good in possession and in the short passing game. Never worth £25 mind.
There were rumours that Lallana had fitness issues at S'ton, rarely lasted 90mins and that was with only one game a week so perhaps that accounts for him not playing regularly after his return from the early season injury.
