A common term in physics

British English version. Make sure you translate the whole text into EITHER British English OR American English. Never mix them (the effect is horrible!!!)

Parlare di centre of gravity mi sembra una definizione troppo fisica; inoltre il centro di gravità può essere il centro campo se 5 giocatori sono in area avversaria e 5 +portiere in area di porta.
In questo caso ritengo che si voglia intendere di tenere abbastanza arretrati i giocatori di centrocampo (midfielders) in modo da stare più coperti, più protetti in difesa


Midfielders *
(Key Concept) (abb. "MF"; aka Halfbacks) Play between Forwards & Fullbacks. Must support the Forwards & also support the Fullbacks. Used to be called "linkmen" because they link the Fullbacks & Forwards. Must run more than any position & must have good stamina or be subbed a lot. On my U-16 recreational team we have 2 "Offensive MF's" ("OMF's") & 2 "Defensive MF's" ("DMF's"). (We play a 3-2-2-3, see "Formations"). My "MF's" move up on the attack & can move into scoring position & score if the opportunity is created. However, they must get back & cover their position & remember they are a mid-fielder. I encourage them to take long chip shots at the top of the goal, but not long grounders that the goalkeeper will easily pick up. On defense, I bring the DMF's back just outside the Penalty Box. We play a zone defense & the Defensive MF's will shift from side to side & move into the Penalty Box if necessary, depending on where the ball is, but the LMF (Left MF) & RMF (Right MF) will not go past the "center"; that way we always have someone covering the center even if the ball is far to one side. (The right and left sides are as you face the other team's goal). (See "Formations" and "Positions").
