The Portuguese giants Benfica have confirmed that their defender Nicolas Otamendi has sustained an injury during training.

The Argentine international is currently undergoing treatment and will be assessed by the club's medical staff before making a decision on his future at the club.

Otamendi has been a key player for Benfica this season, playing in all but one of their games so far this campaign.

He was also part of Argentina's squad for the World Cup last year, where he helped the team to reach the quarter-finals.

The news comes as a disappointment for both Benfica and Otamendi himself, who has had a successful career at the club.

However, it is important to note that the injury could impact the club's plans for the remainder of the season, especially with the upcoming Champions League group stage matches.

It remains to be seen how long Otamendi will be out for,Serie A Stadium but it is clear that he will need time to recover fully if he is to return to full fitness.

In the meantime, Benfica will need to find a replacement for Otamendi, which may require some recruitment work.

Despite the setback, Otamendi has shown his commitment to the club and will likely continue to play a key role in their efforts to win the league title.

For now, fans will be hoping that Otamendi can make a full recovery and return to action soon.
