Jude Bellingham should have been the best option, but he's just too good, the right decision at this period was to choose Real Madrid.
I'm happy for the LFC fans that MacAllister finally seals his move to Liverpool FC but there's no way LFC would have been able to convince Jude Bellingham to sign a contract when Real Madrid is on the radar. LFC lacks champions league football next season and won't pay him what Madrid is offering, also at Real Madrid he's certain of winning major silverwares before his contract runs out.
Rumors about Mac Allister and Liverpool had been swirling for months now and it's been great they are working quickly to bring in this player now. but indeed for Jude now it's a bit complicated I think.
Their rival is Madrid and when talking about Dortmund's business of course big money is the priority so if they really want to hijack Jude then they have to be prepared with bigger money than Madrid.
