Sergio Ramos is right - football is cyclical, says Luis Enrique

Sergio Ramos' assessment of Barcelona's dominance in La Liga that "nothing lasts forever" is correct, says Camp Nou coach Luis Enrique, who nevertheless wants to maintain a Catalan grip on Spanish football.
Speaking on Monday, just over a week on from Barca's crushing 4-0 win in El Clasico, Real Madrid defender Ramos said: "Barca should enjoy this as much as they can, nothing lasts forever."
Former Madrid and Barca midfielder Luis Enrique felt that was a fair comment, telling reporters at his media conference ahead of Wednesday's Copa del Rey clash with Villanovense: "That's an obvious reality.
"Teams work in cycles, no-one is going to win every title. This is our moment and let's hope it continues as long as possible.
"It's logical things will end but the players are working hard to allow us to extend this spell."
Barca won the treble of La Liga, Copa del Rey and Champions League last season and are in irresistible form, winning their last six games in all competitions, racking up 22 goals in the process.
