Tottenham Hotspur have been left extremely impressed by a defender who only left Major League Soccer to move to Europe back in January.Spurs made major changes to their backline during the summer window, with Cristian Romero, Djed Spence, and Kevin Danso leaving the club, while Marcos Senesi, Jan Paul van Hecke, Andy Robertson, and Tosin Adarabioyo arrived through the door.The new-look Tottenham back line is still gelling with one another, but they are showing signs of improvement, with the Lilywhites having conceded just four goals in their last six league matches.It has been widely reported that Spurs want to reinforce one area of their back four in the summer, with De Zerbi’s men reportedly scouring right-backs across Europe.A full-back who impressed in the World Cup for the United States has been added to the club’s wishlist.Photo by JOSE JORDAN / AFP via Getty ImagesTottenham one of several Premier League clubs eyeing Alex FreemanAccording to TEAMtalk, Tottenham have been impressed by the rise of Villarreal’s Alex Freeman, who has come on leaps and bounds this year.The 22-year-old only swapped MLS side Orlando City for Villarreal back in January of this year, but he has already become an indispensable part of Inigo Perez’s backline.The report claims that Spurs are assessing various right-backs around Europe, and Freeman is one of the players to catch the eye of their scouts with his attacking qualities and athleticism.However, Tottenham are not the only Premier League side watching the American, whose situation is also being closely followed by Man United, Chelsea and Man City.Spurs icon Mauricio Pochettino is already a huge fan of Freeman, having managed him with the US Men’s National Team. During the World Cup in the summer, Poch said: “He is so humble, he has an amazing profile, he always listens. You really enjoy being with him, coaching him, and [he] is an amazing player. For me, [he has potential] to be one of the best players at his position in the world.”Are Spurs eyeing Freeman as a potential Pedro Porro replacement?TEAMtalk suggest that the Lilywhites are viewing the Villarreal star as a potential long-term solution at right-back if Pedro Porro departs the club.They point out that Tottenham’s interest in Freeman comes at a point when Porro is wanted by both Real Madrid and Barcelona.However, other sources have indicated over recent days that Spurs are relaxed about the Spanish international’s future, having tied him down to a new long-term contract in the summer. It would take a world record £75m to even bring Tottenham to the table.De Zerbi’s men may simply be keen on adding another right-back to cover for Porro, which would allow Archie Gray to compete for his favoured midfield role.READ MORE: Alex Scott could be about to go from Tottenham fan to Spurs rival after ‘confident’ £100m updateThe post Tottenham plot move for USA star who Pochettino says is 'amazing' and 'humble' appeared first on Spurs Web.
