Kieran Trippier on Eddie Howe
“We have a great relationship. He trusted in me once and he’s trusted in for the second time,” Trippier told NUFCTV.
“I’ve got huge respect for the gaffer. I know what he demands on the training pitch and on the pitch. I’ll give absolutely everything, as the gaffer knows.”
When asked about his conversations with Howe, Trippier said: “We’ve just been brief really.
“He was very excited for me to come to Newcastle, I was very excited to join him for a second time.
“I feel like I can help the team on and off the pitch but the important thing is we all stick together for the second half of the season because every game is a final.
“I’m happy to be here to try and keep the team in the Premier League. That’s our ambition.”

“It’s an honour for me to be here.
“It’s a good team, good manager and good staff. The people that know me, the players and managers I’ve played with know I fight for everything.
“I know the position Newcastle are in but I want to be here and help the club on and off the pitch with my experience as well to climb up the table.
“I’m not shy to get in a battle. I want to do my best for the club, the fans, the owners and everyone involved with Newcastle United. “
