After 8 seasons in Estudiantes, Orenga signed for Real Madrid once more with a bench role but they couldn't win the ACB League after losing the 1997 final against FC Barcelona and being defeated in the 1998 semifinals against the champion TDK Manresa for a tight 3-2 serie.

In Europe Real Madrid won the Saporta Cup after beating Smash Verona in 1997, a great season for Orenga who was named the MVP of the ACB All Star.

In youth levels Orenga won the silver medal in the 1984 Tübingen European Championship U17 after losing the final game against Yugoslavia.

In Spain some players as Sergio Llull, Pau Ribas or Xavi Rey played some years after in the National Men's Team.

After four seasons as assistant coach of Sergio Scariolo and a great success in youth levels winning 3 medals, Orenga was hired as head coach of the Spain national team that competed in the 2013 European Championship where Spain played without some of the stars like Pau Gasol, Serge Ibaka or Juan Carlos Navarro.

In November 2017, Juan Orenga signed for Jilin Northeast Tigers of the Chinese Basketball Association (CBA) in the middle of the competition where his team registered an 8-30 record.
