You should change this from... to POSSESSION football.
"Parking the bus" neutralizes ALL footballing styles. To date, there is NO full-proof method to counteract the "bus".
Rijkaard neutralized Mourinho's bus (Chelsea) in 2006 (after he knocked us out in 2005' 2:1 and 2:4).
Do you know how?
= he didn't play all out attack like in 2005' (Tiki-Taka is somewhat similar to all out attack possession football with all your players in the opponent's half).
-- our team played more safe and cautious and we haven't played with 10 players in their half
-- we "gave" them some Possession and gave them a ball from time to time, and then when they would slightly open and when they would lose their bus-structure, and we would do some faster counterattacks
-- so, we played a regular Possession football in those matches, but not with 10 players in their half
= if we managed to score that way=fine
-- if not, we would give them the ball, and tried some counterattacks
So, what we have today with Tiki-Taka against top teams?
1. we have Possession 70-80%
2. we usually don't break the bus with shortpassing/playing through the middle
3. we don't have a plan B, for example:
a) playing high crosses because we don't have higher players
b) we don't try to give them some Possession to force them to open slightly more and to leave their bus-formation
-- we don't even try some counterattacks, players like Xavi always slow down the game/our counterattacs and it seems like they want to play against parked buses
4. also, with playing 10 players in their half, we usually can't score a goal, and yet, we are very vulnerable on counterattacks and we usually lose those matches
Rijkaard's tactics:
1. we didn't have Possession 80% of time
2. we didn't attack with 10 players in their half
3. we tried a few different styles:
a) through the middle, something like Tiki-Taka
b) we tried some crosses (Ronaldinho was higher than our current players, Eto'o was higher than our current players, Larsson was the king with headers)
-- also, we had more arial ability both in attacking and defensive free-kicks (Puyol, Marquez, Oleguer, Edmilson, Van Bommel, Belletti))
-- so, our team was generally much stronger physically and much better in the air, both in the attack and defense
c) we had even plan C, to give them some possession and to counterattack them with fast Ronaldinho, Eto'o, Guily/Messi
4. We didn't allow counterattacks, because we didn't play with 10 players in their own half and with fullbacks almost in their box
For those who fear that Barca will die without Tiki-Taka, we have always played Possession football and there are 1000s of other variations of Possession football.
Rijkaard's Barca didn't play Tiki-Taka and they brought us the first Champions league since 1992'
Also, current Tiki-Taka is extremely one-dimensional, it is easy to defend, we don't have a plan B and plan C like in 2006', and we are extremely vulnerable on counterattacks.
Seriously, the world won't end if we change our Tiki-Taka to some upgraded/evolved version of Possession/attacking football with slightly more options in the attacks, and slightly better defense against counterattacks and against corners.
