During Real Madrid's first training session yesterday, it was seen that Toni Kroos was mentoring the young players and it is hoped he will set a great veteran example for every young player in the generations to come. I think that not only Kroos but Modric will also do the same to help every young player at Real Madrid to develop more and when the games are difficult they have the winning mentality that has been passed down from a long time ago. Maybe that's why Real Madrid gave Kroos and Modric a contract extension as a companion for young players for the next season. Real Madrid knows very well what is needed at this time to improve the game of its young generation.
Toni Kroos and Luka Modric are expected to be mentors to young players next season because after all the two players have more playing hours and have faced a much higher pressure than the players who are left now. Their presence at the club can actually provide motivation for young players because they both have so much experience in facing important matches and may be true as you say for this reason Real Madrid extended a one -year contract for Luka Modric.
Real Madrid is aware of the role of Toni Kroos and Luka Modric, these two players can balance the Real Madrid midfield with the experience and talent they have. Real Madrid just lost Benzema, maybe because they don't want to lose mentors to other young players, Real Madrid chose to keep them.
Their presence in the Real Madrid midfield can help other players deal with pressure when they are playing big matches, they can also become leaders for other players who are still unstable and selfish due to their importance on individual awards. In a team, there needs to be a leader who can provide motivation and direction when they are under pressure. Toni Kroos and Luka Modric will be very useful in maintaining the balance of the game and building fighting spirit for other players to get out of pressure.
