With his younger brother Phil working as assistant, Gary Neville will take the reins at Valencia for the first time this week. Dimas and David Carrasco, the twin brothers who are leading Europa's charge for the title in Gibraltar, feel working with your sibling is a win-win.
Dimas Carrasco advised the Neville brothers to keep one word in mind as the former Manchester United team-mates work together again. "Unity!" the coach told UEFA.com. "They should both discuss everything they are going to try and put across to the players beforehand and that all decisions need to be made with equal input between them. If there is a strong bond as brothers have, the squad will respond to this unity and become stronger. There is no honesty and clarity like the communication between siblings; they should use this to their advantage."
Coach Dimas says having brother David as his assistant is something special. "The relationship between my brother and I goes beyond family," he added. "We are aware we are a special case as we are also twins. We both know that together we double our capacity to work and like this we can achieve more.
"When we work together shoulder to shoulder, we complement each other and our working partnership is nearly perfect. We have been working together since birth! When it comes to training sessions, analysing rivals, directing matches, four eyes are better than two. Sometimes we don't even have to communicate verbally – our minds work as one and we can understand each other with just a look."
