Can makes Spurs move Permanent in £25.5m Deal

As Tottenham gear up for next season, manager Pochettino has made his first move in the transfer market, sealing a £25.5m deal to make midfielder Emre Can's loan deal a permanent affair. The German midfielder has spent the last 18 months on loan in London, and established himself quickly as an integral part of Pochettino's side.
During his loan spell, Can made a total of 47 appearances, scoring 3 goals, and forging a reputation for being one of the most commanding holding midfielders at the club. This season, he was inducted in the club's overall best XI, and named in the seasonal best XI, narrowly missing out on being the fan's player of the year to England starlet Harry Kane.
Speaking to Sky Sports, Can was positive about the deal to keep him at Spurs, saying:
"It's been a really great experience, playing here for the last 18 months, and to be as close to the fans and my team-mates as I am, I couldn't have imagined going back to Liverpool. Tottenham, and Mauricio, have been excellent to me, and I can see a long and successful future with this club.
My main priority is to grow as a player and learn from the very best, and it's a massive honour to be fighting for a midfield spot along side Lucas [Romero], Martin [Odegaard], Christian [Eriksen] and Pierre [Emile-Hojberg]. They're all great guys, and we get on very well. It's great to go to training, knowing i've just signed a contract until 2021, and really feel like part of a unit. The squad has really gelled this year, and I think we could be a real force in the coming season."

Christian Eriksen has spoken highly of Can, suggesting the youngster could become one of the best
As Spurs team-mate Christian Eriksen signed a one-year extension with the club, he spoke highly of Can, and even suggested that he could become one of the best the club has ever seen:
"When people talk about great midfielders, they always talk about the Xavis, the Messi's, the Ronaldo's of this world. Players who can pick out a pass from miles away, and who have the dribbling skills to beat an entire team. It's not often that they talk about players like Emre, who can break down opposition attacks all day long, and then find a killer pass to suddenly put their team on the front foot. But that's what he's very good at. We've seen that over the last 18 months, and we've all watched him develop into a world-class player.
I won't lie, it makes me scared for my place in the team!
But that's a good thing - it's great to have him train alongside me, and he pushes me every day to become a better player. I think one day he will be spoken of in the same breath as Messi and Ronaldo."
Perhaps Eriksen is a bit over-excited, but this deal is great news for Spurs fans
