I don't think we need any new strikers, we already have olivera and kapo who can play in the strikers role now. They can produce better than any newcomer . i think kapo would be the key in period coming as well as olivera.
About the messina match i think that 4-5-1 is the best way to go, camo isnt producing his best game so it should be like that:"
--------------------------------gigi-----------------------------------
-----------zebina----thuram----cana-----------------zambro
----------------------blasi----------------------appiah(tacchi)-------------
----------------------------------emerson----------------------------
---------------neddy-------------------------------------oilvera----------
-----------------------------zalayeta---------------------------------
this formation is the most balanced i think, and gives us more attacking as well as defending options. And its somehow similar as the one dpforever put in but more attacking options as neddy and oilvera can attack with emerson supporting, and he wouldn't have to worry about defending.
and on the wings zambro and zebina can attack and blasi and appiah can cover their places, becuz messina have a good counter attack.
