TAA is injured it is probably worth using the transfer to remove him and bring him back in with your wildcard/future transfer later, when his price has dropped. I'm only saying 'cos I read he is guaranteed out for two weeks.

Gunnarsson plays for an extremely shit team, surely we can find someone better with 6m, what about Pereyra?

This is my opinion, Strikers score only 4 points for goals and don't get assists and we have a tonne of fantasy midfielders that are up-front irl who are bloody good, I would put two premiums up top I wouldn't say Kane or Auba are especially more likely to return over christmas than Hazard you can upgrade Gunnerson then and still have players like Wilson and Jiminez (who I would pick long before Mitro btw)
