#3: The players and culture
Real Madrid is the most star-studded team around the globe. They have the best players for each position with the likes of Cristiano Ronaldo, Toni Kroos, Luka Modric and Sergio Ramos all plying their trades for the club. There is no doubt that these players are a cut above the rest in football.
Needless to say, there is a big amount of ego in the dressing room at the Bernabeu. The Englishman will have to watch each and every word if he wants to get into the good books at Real Madrid.
Kane might be banging goals every week, but it's a totally different scenario when you play with players that are a shade more skilful than you. At Tottenham, Kane is easily the best player. But, a sudden transition of quality from the Lilywhites to Real Madrid would extend the level of pressure in which he might find it hard to adjust.
Also, Madrid represents a totally different culture and a different language. Players who don't speak fluent Spanish are easy targets for criticism. Gareth Bale has shown no interest in learning the language and hence there's always a barrier of communication that has led to meagre bonding with his teammates.
Even Toni Kroos experienced problems with the dialect in Spain. The language barrier stunts personal relations with players. If there is no attachment with teammates, the effect is clearly visible on the pitch. Language is crucial for a swift co-ordination with players, and Harry Kane needs to spare a thought about the same.
