Considering the statistics of Muller I decided to put him on market and try to get another PT with a lower quality but that can score some goals instead.

Can you give me Tips on how to find a ST that can do his job instead of chilling?

Thanks

these are pretty good for level 2 ..... buy one which is one-one scorer . ..or do you have a good midfielder to support them ?

18 years old and most expensive but it is hard to get them, maybe 15 tokens enough

I play with butterfly with 2 am l/r.

I tried to get a one-one scorer but was too expansive :/
