Sandro Tonali has officially signed for Newcastle by a 70 million euro transfer fee. This is a really good start to the transfer window I think. Because he is a really talented defensive midfielder and he can make the line between Newcastle defense and midfield stronger now. However Newcastle should continue to make more transfers to build a solid team to maintain consistency in the Premier League and do a decent job in the Champions League on one hand.
I don't expect Newcastle's Champions League target to be more than reaching the group stage though. But if they have a good draw they can do a really good work thanks to having a stronger lineup and a solid cooperation among the players.
