Olic is 34 - Sturridge is in his early 20's.
At the same age I would have taken Olic - quality striker.
Matic and Fernandinho are different types of players as well
Lallana has had a good season - played well no doubt and think he could be a good player for our squad but let's not go to,overboard on him until he we see more than a good season
He was good year before that, and the two before that (albeit in lower league).
At the end of the day, if he goes it'll be for £25m, but it's not happening til end of July.
Re the other players mentioned, whilst they do have the greater experience, neither was in particularly great leagues either.
As as I said, having watched him play 200 games plus, lallana can play anywhere from midfield forward and other than a ball winner is better than both of this players.
When end you sign him, I've no doubt he'll be first team within 3 months.
