Nottingham Forest's on-loan defender Gonzalo Montiel must head back to Sevilla in January.

The Argentina international has been at the City Ground club since the end of August.

However, the 26-year-old has not impressed at Forest in the way that people were expecting.

Per Estadio Deportivo, his situation is described as “unsustainable," given Montiel is lacking playing time.

Forest could have signed him for a modest fee if he played 50 percent of their games.

However, he has only started three games this term, which means Sevilla could recall him in January.
