My favorite sport is football . Football is very interesting and useful sport . While playing fotball sportsmen namely footballer develop his or even her reaction , coordination and co-operative skills like team work , perfect passes and e.t.c. Also, from my point of the view it is the most popular and colossal sports . For example player transfers in football cost many milions euros. Almost everybody knows football , milions of fans under no circumtences watch football matches online . However football clubs and players make really huge contribution in charity . Everybody loves football .
Довольно и понятно , рад был
