Roberto Carlos scored the winner in the 3-2 victory over Recreativo Huelva and put Real back on the top of the Liga table.
Capello said: “It was incredible.
“Roberto Carlos ran over 80 metres to support the attack. It shows the players have the team ethic coursing through them.
“We gave away both goals, but we have played a great game. We deserved to win the encounter because we created a number of clear chances, but this is football. When you relax and the opposition is very good, something can always set you back.
“Roberto Carlos’ was an important goal, but we can’t say we have won the title because of it. There’s still three games left.
“We’re all delighted for Roberto Carlos and for ourselves.”
