That's a theory that wouldn't work in reality. Messi in midfield, without Rakitic or Iniesta? To accomodate another top striker? This makes no sense at all. What would be the point of that, anyway? Another forward would only make sense to rest one of MSN. No to mention all that would completely change the tactics and way of playing of the team. And I can't think of a top striker that would play only when/if the team got a decent lead. Meaning no important games. There's no need(or money) for another top striker, anyway. Just a good sub.
1. Players want to train and play with the best. Oh, and win trohpies of course.
2. I am not suggesting that Messi should play 90 minutes on our midfield.
3. Rest one of MSN? Messi has missed 27.5%, Neymar 25.5% and Suárez 15.7% of all minutes played this season. I think they have had enough rest. It is not like they need more anyway, their numbers are staggering. It is only a matter of time before they top their numbers from last season. 107 - 122 goals. 51 - 55 assists. Another thing you should take into a count, they won't accept being subbed. Last season should serve as a reminder.
4. Again, I am not suggesting that we change tactics, system or anything else, other than playing messi on our midfield for 25-30 minutes at the end of some games. Let us not forget, he tends to drop back a lot after he has scored 1-2 goals, he then looks for his teammates and tries to help them score, why shouldn't he be able to do that from iniesta's position for 25-30 minutes and let another player take his?
5. When/if? .. please.
This season:
11-08: F.C. Barcelona - Sevilla = 90 minutes (Neymar not playing)
14-08: Athletic Bilbao - F.C. Barcelona = 90 minutes (Neymar not playing)
17-08: F.C. Barcelona - Athletic Bilbao = 90 minutes (Neymar not playing)
23-08: Athletic Bilbao - F.C. Barcelona = 90 minutes (Neymar not playing)
29-08: F.C. Barcelona - Málaga = 3 minutes (Neymar subbed off in the 87th minute)
12-09: Atlético Madrid - F.C. Barcelona = 59 minutes (Messi subbed on in the 59th minute)
20-09: F.C. Barcelona - Levante = 90 minutes (Suárez not playing)
26-09: F.C. Barcelona - Las Palmas = 81 minutes (Messi subbed off in the 9th minute)
29-09: F.C. Barcelona - Bayer Leverkusen = 90 minutes (Messi not playing)
03-10: Sevilla -F.C. Barcelona = 90 minutes (Messi not playing)
17-10: F.C. Barcelona - Rayo Vallecano = 90 minutes (Messi not playing)
20-10: Bate Borisov - F.C. Barcelona = 90 minutes (Messi not playing)
25-10: F.C. Barcelona - Eibar = 90 minutes (Messi not playing)
28-10: Villanovense - F.C. Barcelona = 90 minutes (Messi, Neymar and Suárez not playing)
31-10: Getafe - F.C. Barcelona = 90 minutes (Messi not playing)
04-11: F.C. Barcelona - Bate Borisov = 90 minutes (Messi not playing)
08-11: F.C. Barcelona - Villarreal = 90 minutes (Messi not playing)
21-11: Real Madrid - F.C. Barcelona = 57 minutes (Messi subbed on in the 57th minute)
24-11: F.C. Barcelona - Roma = 26 minutes (We are leading 5-0 in the 64th minute, when Enrique decides to sub off Roberto for Adriano on the CM position, no reason Messi couldn't have played there in the remaining 26 minutes)
02-12: F.C. Barcelona - Villanovense = 90 minutes (Messi, Neymar and Suárez not playing)
09-12: Bayer Leverkusen - F.C. Barcelona = 90 minutes (Neymar and Suárez not playing)
12-12: F.C. Barcelona - Deportivo = 90 minutes (Neymar not playing)
17-12: F.C. Barcelona - Guangzhou Evergrande = (Messi and Neymar not playing
20-12: F.C. Barcelona - River Plate = 1 minutes (Neymar subbed off in the 89th minute)
30-12: F.C. Barcelona - Real Betis = 4 minutes (Roberto subbed off in the 86th minute and replaced by Munir)
He could have played 1851 out of 2610 minutes before New Year. 20 x 90 & 51 minutes. Again, not taking into a count the times Messi could have been moved back into a AM position for the remaning minutes, when we had a 3-4 goal lead.
