Well in Spanish we have a slightly different meaning of the word tactics. The above would be a "formation" and the tactics would be the different automatised movements that are trained in the training sessions and are put in practice in the games.
I'd like this thread to be about that. I consider I have a very basic knowledge about tactics, but I think that I can learn from many of you, that's why I write this post.
I'll start the thread by commenting two things I saw from Rafa's body language, and no it's not that he was unconfortable

Xabi's long balls
At min 60 the camera focused on Rafa, who was yelling and making signs. He first made a curve with his hand as in "long ball or game orientation change". And then he put one finger of each hand upwards and swithed their position, from back to forward.
The super footie pundit of ITV said
"Well I think that he's asking Bellamy to start his runs from deeper positions and not to be square to Kuyt".
I don't think he meant that, because he yelled "Xabi, Xabi!" for starters. Then I read in his lips the "largo (long)" when made the curve with the hand. And then he said "Aqui, no aquí" that is "(do the long ball) Here, not here".
I think he meant that Xabi shouldn't do a long ball when he had his partner midfielder (Sissoko) behind him, but when he was in a deeper position than Sissoko, so that the midfielder that is onfront of him help the pass receiver and he (Alonso) covers the back just in case.
The fingers where like this
X
Al. (this would be Alonso) --> Here!!
Al. Not here!!
-------X --->
I'm pretty sure about he was talking about the long balls (side to side), not sure about my interpretation, if any of you can watch again the game, or remember that please tell me.

Hope you understood the schema, because I'm pretty sure that I couldn't express well what I wanted to say in english

The "come" gesture
A gesture that Rafa does often is one that asks players to "come here". He does that when we are defending. When ever the oposition pass the ball horizontally or backwards. Rafa starts to say "come here" (sometimes really angry) so that we do not stay too deep and we leave the oposition forwards in off side. That's something LFC does regularly very well and a pleasure to watch.

You may talk about this kind of tactics here. Things like zonal vs marking defending, how well was the defence coordinated, the threat that is caused to oposition when Gerrard initially on a wing swaps position with one od the midfielder, and things like that
I love it when someone that knows more footie than me comments some of this movements. Most of them are used often and when you realise that on the match you sometimes appreciate more the job some players do.
