Croatian midfielder is due back in training with Real Madrid this week following his extended break.
Mordic, who has been away on an extended break after his World Cup commitments with Croatia, will come back to a squad containing both Kroos and Rodriguez, who will be vying for his position.
The arrival of both names will threaten Modric’s chances of appearing game-in game-out for Madrid as he did last season, but has still welcomed their arrival.
"I watched James Rodriguez and Toni Kroos play in the World Cup and, for me, they were two of the best players in the competition," Modric told Spanish newspaper Marca.
"They're great players and will only improve our team even more.
"Real Madrid have shown their ambition by bringing such fantastic signings to the club. It's great news for us, the players, because we always want to play with the best, and also for the supporters, who want to see the best players."
The arrival of Kroos and Rodriguez has reportedly signalled the end of several careers at the Bernabeu, as Real Madrid now boast tremendous depth in midfield.
Sami Khedira has been linked with a move to Arsenal, while Angel Di Maria and Isco have also been rumoured to be on their way out of the club.
To fit Kroos and Rodriguez in to a system that also accommodates Cristiano Ronaldo, Gareth Bale and Karim Benzema will certainly be challenging for Carlo Ancelotti, as they risk losing balance in the midfield.
Should Sami Khedira leave, 32-year old Xabi Alonso will be the only high profile midfielder with a more defensive mind-set, and with Madrid competing for six trophies this season, they can barely count on him for a 60-plus game campaign.
