Cheese, download the tactic and put it in your tactic map in the FM map.
Then try signing either Ventrone as your assistant, if he rejects you try Leonel Pontes. Let your assistant stay in charge of the team talk. See how it goes.
As far as the mercato goes, it's up to you to sign whoever you want.
