After reading this article I thought it will be a nice ideal to make your favourite formation by picking young players not more than 23 years old from each team( You are allowed to pick only 4 players that are above 23 of which they must be 1 player in attack above 23, 1 player in midfield above 23, 1 player above 23 in defense and lastly a bonus pick a player above 23 from any position including goalkeeper, your bonus is most most likely be a goalkeeper) to challenge Barcelona starting line-up in the final.

You must pick at least 3 players from one of the three clubs and at most 4 players from one team of the three teams

Hard to come up with starting line up to challenge Barcelona with all the rules, but then again it allows you to display your tactical knowlegde in football and experience the difficulties in becoming a manger, rather than just having all top players to choose from.

You most also choose you captain

Here is my line up.

--------------------------Cassilas(C)------------------------
Boateng------------Lucio---------Ranocchia------Marcelo
---------------------------Sahin-------------------------
------------------Sneijder----------Kroos-----------------
----------------------------Oezil-------------------------
---------------------Forlan------Gomez-------------------

Edited: rules slightly changed to accommodate a better line-up and gives room for more formation.

--------------------Pacheco------------------------
Boateng-------Varane-------Ranocchia-----Marcelo
---------------Sahin---------Kroos----------------
-----------------------Özil------------------------
----Higuaín---------Benzema-----------Ronaldo

New Rules:

------------------Julio Cesar-----------------------
----Ramos---Varane---Ranocchia---Marcelo---
------------------Zanetti----------------------
-----------Sahin----------Kroos--------------
---Özil-----------Benzema---------Ribery---

Kind of hard when Inter is a option, they have no players under 24
