Alex Fernandez says Real Madrid Castilla are showing great character on their Segunda Division return.

The Castilla edged Las Palmas 3-2 on the weekend to maintain their impressive start to the season.

"We cannot let our guard down. When Las Palmas drew level at two-all, we reacted very well as a team. The team is maturing little by little; this is a very difficult division, but we are in a privileged situation, where we can look upwards and deploy our style of play," said midfielder Alex.
