To conclude the trio, Vanja Savic is a great pickup if you can persuade him to leave Manchester United behind. He's solid across the board, and often that is exactly what you need from a goalkeeper. The 18-yer-old Serbian is commanding in the air, already armed with decent distribution, and comes with the hallmarks of a great addition to many squads. It's so hard to determine how good teenage goalkeepers can become, but theses options are all worth taking a punt on.
