Hard to know where to start! Carry on how you are and I foresee disaster.
If you have access to a good sports physio/injury therapist go to one.
Ligaments take a long time to heal, and the associated muscles will have weakened while you were (presumably!) inactive with torn ligaments.
Achilles tendonitis is something I am familiar with and is a separate issue. Holding the achilles in place with strapping, etc will make it worse. It needs to be able to fully extend and not be held in position.
So, you will need to keep the strapping off, and also stop football.
The ankle muscles will need to strengthen which you should do with gentle, controlled, low-intensity exercise such as slow running on smooth, flat surfaces.
You'll need to do regular stretching for the achilles and calfs The best stretches are heel drops off a step, but using your arms/upper body strength to bring yourself back to the level position (eccentric heel drops). Do not use the feet and ankles to bring yourself back level and certainly do not do heel raises or any other activity involving going on tiptoe. Do the stretches with knees bent, and also knees straight to activate different calf muscles.
That's probably enough for now! Do some research on achilles tendonitis (inflammatory), which in its chronic form is more correctly called achilles tendinopathy (degenerative, non-inflammatory).
