It is Master League, it allows you to transfer all kinds of players, any player you ever dreamed of being in your team can be there. That is the point of Master League, to live out your football dreams virtually and build the best team ever. I personally when I choose a team, I use the players from match mode and then from there sell some players and buy some. It usually takes me 4 seasons to acquire the players I desire since I start off with 8000 cash only and in 2nd Division. Then once I have all my players I go for D1 Cup, UEFA Championships, D1 League and what not. By the 5th-6th season I go out scouting for new young players as most of my squad is probably close to reaching it's peak. That's the cycle, I personally enjoy it this way but I guess everyone has their own way.
