Real Madrid welcomed back Toni Kroos, Marcos Llorente and Mariano Diaz to training on Tuesday ahead of their Copa del Rey game against Girona

Upon returning from their triumphant Club World Cup campaign in December, Real’s start to 2019 hasn’t exactly got off the way they had planned.

In the six games played so far, Santiago Solari’s men have only claimed three victories as their struggles to hit top form continue in the new year.

Injuries have played a part in this, with both Kroos and Llorente having been struggling with adductor problems over the past month.

Meanwhile, striker Diaz has been sidelined since the beginning of January with a back problem after pulling out of Real’s 2-2 draw at Villarreal in La Liga.

Despite taking Cristiano Ronaldo’s old number seven jersey at the Santiago Bernabeu, Diaz has failed to make the impact Real had hoped for when they re-signed him from Lyon in August.

The 25-year-old’s difficult season hasn’t been helped by two hamstring problems, which ruled him out for the first few weeks of November before spending most of December sidelined.

But Real confirmed on their website that Diaz, along with Kroos and Llorente, returned to full contact training on Tuesday morning.

Top 5 most disappointing clubs in Europe this season

It's time to discuss which clubs in Europe have been the biggest disappointments this season, we'll talk about the Top 5 Leagues for this...

This could put them in contention for a place in the team that takes on Girona in the first leg of the Copa del Rey quarter-final clash on Wednesday at the Bernabeu.

Castilla players Cristo and Javi Sanchez were also involved in the senior team training session, which suggests they could be in the squad.

However, Keylor Navas and Jesus Vallejo both continued to work away from the first-team as they work on their own individual recoveries separately.

Gareth Bale and Marco Asensio were also seen outside at Real’s Valdebebas training ground, but didn’t train alongside their teammates.
