Manchester United midfielder Ander Herrera has taken to social media to showcase his fighting skills ahead of this weekend's crucial match against Everton.
United take on the Toffees as part of Nissan Super Sunday, live on Sky Sports Premier League, and Herrera appears to have opted for an unusual form of training in the run up to the match at Old Trafford.
The 28-year-old midfielder took to Instagram to post a video of himself practicing with the pads at a boxing gym in Altrincham.
The Spain international also laid down a challenge to David de Gea by light-heartedly claiming he would punch his team-mate the next time they met.
Red Devils boss Jose Mourinho will no doubt be hoping to see that same fighting spirit from Herrera as the season progresses.
