From what I've seen of Luque, he's not an orthodox out and out striker. plus its well documented he's more than comfortable playing a withdrawn and even a wide role.
I'll be suprised if, when considering '4' (or whatever number of strikers rafa thinks we should have) he is counting le tallec in the list. I just dont see the lad as a striker, and I certainly dont see him as a first team player this season. Wouldnt be suprised if we try and ship him off somewhere, be it on loan or permanent.
Which leaves our strikers at Crouch/Moro/Cisse/pongo. im presuming Baros is off, seems that rafa has had enough of both his playing style and mentality.
As a result, someone like Luque would be fantastic. As much as I like pongo, I wouldnt be comfortable having to rely on him starting a succession of games should we get more injuries. Luque would easily fill the void of the '4th' experienced stirker, whilst also filling options wide and in behind.
As for the 'pace',. players like carew, mista etc at valencia had little pace up front. Seemingly rafa rates link up play as more important than pace. Whilst pace is obviously an excellent attribute to have, I think the days of the ball over the top and chase it are over. Strikers need to be more versatile than just utilising pace.
