Madrid - Real Madrid president Florentino Perez insists the European champions' squad is "impossible to improve" after an uncharacteristically quiet transfer window.
Perez, known for splashing hundreds of millions of euros in previous years on the likes of Cristiano Ronaldo, Gareth Bale and James Rodriguez, has limited his spending to just a €30 million buyback of Alvaro Morata from Juventus.
"We have won the European Super Cup and the first two games in La Liga," Perez said of Real's 100 percent start to the season.
"We have a spectacular squad and it is impossible to improve."
Madrid appealed a one-year transfer ban imposed by FIFA to allow them to sign players this summer, but they could be barred from registering new players after Wednesday's deadline until January 2018 should their appeal fail.
Zinedine Zidane inspired a remarkable turnaround in Madrid's fortunes after being hired as coach in January, leading Real to an 11th European Cup.
The Frenchman hinted early in the window the Spanish giants would be quiet in the transfer market and, having conquered Europe, the pressure is now on Zidane to deliver Madrid's first league title in five years.
"Zidane, all his technical team and the players are very aware of their responsibility and want to show what they are capable of," added Perez.
