Real Madrid defender Sergio Ramos has urged his teammates not to get away with successive victories over bitter rivals Barcelona.
The defending Spanish champions won 3-1 at Camp Nou last week in the Copa del Rey semi-final second leg and on Saturday registered a 2-1 home victory over the Blaugrana in La Liga.
"We are enjoying a period of tremendous satisfaction," El Pais quotes Ramos as saying. "Now more than ever we have to keep our feet on the ground.
"We've won two Clasicos in a row against Barcelona but haven't achieved anything yet. One of those victories helped us to get into the Copa del Rey final while the other saw us cut the gap to Barca at the top of the league to 13 points.
"In reality, the main advantage of these two wins is that it means we are going into Tuesday's game against [Manchester] United in very good spirits."
Madrid will take on Manchester United in the second leg of their Champions League last-16 tie at Old Trafford on Tuesday, having drawn the first leg 1-1 at the Santiago Bernabeu last month.
