The versatile defender/midfielder has put pen to paper on a new deal that runs until 2020.
Snapped up from Sporting Lisbon in July, 2014, Eric made quite an impact in his debut season.
It all started in dream style with a last-minute winner at West Ham on the opening day of the season and playing in right-back and central defensive roles, Eric went on to play 36 times in all competitions.
Firmly part of Mauricio Pochettino’s squad, the England Under-21 international has adapted superbly to a new midfield holding role this season and speaks with enthusiasm when asked where he sees the club at the moment.

“If you look at the Training Centre, the young squad, the new stadium coming through - the club is in a great place and as long as we stick together, everything is looking very exciting,” Eric told us on Wednesday.
“There is a great core here of young players and even the likes of Christian, Erik, Kyle and Danny are all still young. We have a young team, a core of young English players and young players in general and there is such a great future for the club.”
Eric, 21, admitted his 36 appearances were beyond his expectations last term. “I believe in myself and my quality but I didn’t really know what to expect and I didn’t think I’d play that many games,” he reflected.
“I said at the time I’d try my best and see where it took me, and it’s taken me here. I was really happy with my first season but there is still a lot of work to do, I need to keep improving and I’ll keep on giving my best.”
As for the club, Eric knew plenty about us before he joined but said our summer Tour of Malaysia and Australia really opened his eyes to our worldwide appeal.
“I always knew it was a big club when I signed but to come here and play in the Premier League, you realise how big the league is and how big this club is in the league,” he said.

“You go to away games and the away end is packed and our fans are making as much noise as the home fans, it’s amazing. When you play at the Lane it’s brilliant as well, an old stadium packed with history.
“Then when you go on Tour, as we did at the end of the season, I’d never been on a trip like that before and it’s amazing how many fans we have around the world.
“It was a massive eye-opener to go to Kuala Lumpar and Sydney and see fans everywhere. You walk down the street and see an Australian Tottenham fan, amazing. All the lads were taken aback. That’s when you realise how popular the club is all over the world.
“I loved every minute of my first season and to now sign a new deal for another five years, I’m happy and looking forward to the future.”
