I received this attractive offer from my friend for my 21 yr old defender, with an ability of 90~%.
He offered 41 mil plus 7 tokens.

The thing is that I would only have 2 defenders left in my squad, both 22 at 94~%.
I sometimes play the third defender for countering formations.

I don't know how I will be able to find a good replacement for him.

Also, this offer ends tmr morning, so I'm looking for quick advice if anyone happens to stumble on this thread.
Thank you.
