Can someone explain how Balance can be increased? I spent my 150 buying my team. I have a balance of 0 and although I have 4 'free' transfers I can't transfer someone onto the team unless they are cheaper than the rider I remove. So I don't understand what a 'free' transfer is. I've read through the 'How To Play' page, but can't find anything. So how can balance be increased so I can buy better riders?
