The Argentina international, wearing a Barcelona vest, punches the air in celebration after the derby win . The United centre back has begun to find form for Louis van Gaals side since his 16million move from Sporting Lisbon in the summer. Rojo has formed a tight bond with fellow defensive partner Phil Jones, who last week expressed his joy at how quickly the 24-year-old had settled in. Jones told manutd.com: Since Marcos has come hes played the right way and in the way weve wanted to play. Its difficult to come over to a different country and a different league and go straight into the team and hit your form, but hes done well.
