At Real Madrid, Paz would face stiff competition for playing time, particularly in the number ten position. Xabi Alonso has several attacking options, including Jude Bellingham and Arda Guler, who are further along in their development. Paz would also have to contend with Kylian Mbappe, one of the best players in the world, for a spot in the starting lineup.

Chelsea, on the other hand, has a more open door for Paz. The Premier League side has limited options at the number ten position, and Paz's arrival would fill a gap in their squad. He would also be joining a young team filled with other Argentina internationals, creating a positive and supportive environment.

While Real Madrid holds the upper hand in this situation, Chelsea would be the best option for Paz from a footballing perspective. The Premier League side's financial pull and lack of competition for playing time make it an attractive destination for the young midfielder.

In the end, Paz's decision will be influenced by a combination of footballing and emotional factors. He must weigh the benefits of playing for Real Madrid against the opportunities offered by Chelsea.
