I have also

[azz]

Can one say
a. He says he has played professional football. Big deal! I have also played professional football!
b. He says he has played professional football. Big deal! I also have played professional football!

Many thanks.

I prefer the first.

The first is much more natural.

Of those two, the first is much preferable. However, note that most native speakers wouldn't use such a repetitive third sentence. They'd say "Big deal! So have I!"
