Football is a competitive team sport played between two teams. The objective is for each team to score more goals than the opposition within the allotted time through formal rules and informal expectations of behavior. Players have different roles on the field and teams employ different formations and strategies to exploit weaknesses and strengths. Physical attributes like speed, strength, and stamina are important for players. Skills are developed through gradual progression of difficulty and repetition of whole skills and specific parts. Warm-up is essential for physical and mental preparation.
