Pre-Contract Players Jan 2020

Hey Guys,

I've been eagerly waiting on my Manchester United save to reach the Jan transfer window so I can sign Eriksen and Cavani on a free.

January has come but there is no option to sign BPL players like Eriksen, Silva, Fernandinho etc on a pre-contract.

Does anyone know why?

Due to English rules you need to wait until the end of the season before being able to offer a pre-contract to any players in England
