The England full-back joins from Atletico Madrid.
Newcastle United have signed England defender Kieran Trippier from Atletico Madrid for an undisclosed fee on a 2 and a half year deal.
The 31 year old is the first acquisition of the club's new Saudi owners.
Speaking to NUFC.com; Trippier said:
"I'm delighted to be joining this fantastic club. I really enjoyed my time in Madrid, but when I became aware of interest from Newcastle United, and having worked with Eddie Howe before, I knew this was where I wanted to be.
🗣 "It's an honour for me to be here."— Newcastle United FC (@NUFC) January 7, 2022
"I'm aware there is a lot of work ahead of us but I know the demands of Premier League well and I know what an amazing club this is with very talented players. I can't wait to get started and I'm excited to step out at St. James' Park as a Newcastle player."
It's expected to be the first in a string of new signings for Newcastle during the January window as they look to retain their Premier League status.
