The 18-year-old has been in excellent form for Reading's youth team this season, and has become an established part of the England U-19 team.
After scoring 15 goals for club and country so far this season, Loader has attracted the interest of a host of European clubs who are looking to find the next Jadon Sancho or Reiss Nelson.
Scouts from Borussia Monchengladbach, Hertha Berlin, Lille and Wolfsburg were all reportedly in attendance as the English youth side routed Moldova 4-0.
With opportunities in the Reading first team seeming hard to come by for the youngster, even though they are struggling in the Championship, it could see yet another English talent go abroad to gain experience.
