Some Liverpool fans have questioned why Trent, if he wants to join Real Madrid, would not have signed a contract extension to allow the Reds to secure a transfer fee. The answer is simple- it would drastically reduce his signing-on fee.
If he joins Madrid with no transfer fee, his signing-on fee would be huge. Add that to weekly wages and he'd be set to earn £600k or more per week for the duration of his contract.
IF he joins Madrid, that would be a big determining factor for he and his brother/agent.
Another factor to consider in the Trent contract situation is that his agent brother, Tyler Alexander-Arnold, would stand to pocket significantly more money by brokering a deal with Madrid than by negotiating a contract extension with Liverpool.
