Messi is such a unique player, he wants to be the main playmaker of the team but at the same time the big superstar goalscorer as well and a reduced role isn't something he would accept. Considering the wingers in Barcelona primary role is to work hard defensively and run for through balls offensively,
I would have Muller as my first choice if I had to use Messi in his peak. Then the question would be who would complement them the best and I would probably go for Pedro on the left considering Henry's dip in form when Messi/Ibra played as false-9s with him on the wing.
"Henry who had combined with
Lionel Messi and
Samuel Eto'o to score 100 goals between them that season.
[43] The trio was also the most prolific trio in Spanish league history, scoring 72 goals and surpassing the 66 goals of
Real Madrid's
Ferenc Puskás,
Alfredo Di Stéfano and
Luis del Sol of the 1960–61 season"
I would have stuck with that 08-09 trio, but then thrown in Ribery in the mix.
I would probably start with Ribery-Henry/Eto'o-Messi and then if I went a goal up I would sub Ribery out and keep Henry-Eto'o-Messi who were scary together when they got a little space to work on. I would start Eto'o probably so Henry could come on with fresh legs after the team went a goal up as he stated he was tired after all the pressing for Barcelona I believe.
