Juggle / Pop and tip
In chinese, 颠球. Juggling is a good practice for obtaining the good sense of touching and controling the ball. It could happen to lots of body parts, usually starting from both feet, then to knee, head, etc. When juggling with the feet, touch the ball with the middle part of laces. Seeing that juggling is hard to start, the practising phases could consist of: toss the ball and juggle with one foot once, and after you are doing good with that, toss and juggle twice, and then three times to even more. Then juggle between both feet.
The several principles of defense:
- Keep close to the opponent forwards. The amatuer team always commit mistakes as this. I found little of such condition in World-class competitions, such as Worldcup.
- Put more defenses than opponent forwards. Can you imagine a team with less defenders than opponent forwards? Yes, it often happens sometime in amateur teams but not in World-class competitions, where the defense/forward ratio is about more than 2, e.g. at least 6 defenders to 3 opponent forwards.
If you once played as a forward, you will know that the weakest moment for a forward is just before him receiving a pass from a teammate. Therefore the defender should find such a moment and break in in time. As to the forward, he thus needs to run to appropriate position from time to time to stay away from defense and ensure the pass is secure.
The second weakest moment for a forward is when he carrying a ball at a very fast speed, and worsen is if there is a opponent defender chasing behind closely. The defense should be done by another defender to cut right into the moving direction of the forward and tackle the ball.
Agentina has lots of excellent attackers, such as Messi, Aguero, Gonzalo Higuain, Lavezzi, Di Maria, but they lacks excellent midfield and defense, which poses a big problem for them in choosing a good system. In history, Argentina foot team always used 433 or 343 system to emphasize attack. However, in such a system the defense is weak and the mid-field can't send good pass to their attackers. Maybe that's why the coach wanted a change. But the result was not so good. The news in 2014 Brasil Worldcup said Messi was busy with both attacking and mid-field passing in 532 system so that he did not behave well in either shooting or passing. The reason is, Messi has been accustomed to the mid-forward region. When the coach adjusted the system to be back to 433 in the second half of the match, Messi didn't need to move back to pass and organize attack, what he only needed is to break through and score. The page also said in this match to Bosnia and Herzegovina (BA), Agentina 433 system still presents its intrinsic defects - the weak defense allowed BA a score. And also, Argentina needs a good mid-field to sew their excellent attackers well.
Netherland team traditionally uses 433 because they always have excellent forwards too. However in Brazil 2014 Worldcup, in winning the match against Spain by great margin of 5 to 1, they used 532.
I always adore the German style, the 4231 system.
