Do cleans, squats, bench, deads, either b/b or d/b rows, dips and shoulder press.
If you want to through in some sort of curls and tricep movements, then go for it, but keep it simple.
Your goals for football should be speed and power into contact.
The best way to build speed is doing cleans and sprints.
Cleans, bench presses, squats and deadlifts are all great power and size builders, keep the reps inbetween 4-6 and do no more than 5 sets for each.
I play rugby and do cleans, rows, bench, shoulder press, squats and pushdowns for the triceps, I also do quite a bit of forearm work as i feel it helps my 'hand-offs' and increases most of my lifts because my grip strenght is now better.
Good luck buddy, train, eat, rest....grow
