London, December 5: Manchester United manager Jose Mourinho joked David de Gea was the club's third best goalkeeper, behind Sergio Romero and Joel Pereira.
De Gea was in incredible form in United's 3-1 Premier League win over Arsenal on Saturday, making 14 saves at the Emirates Stadium.
But Romero will start for United against CSKA Moscow on Tuesday and Mourinho said the Argentina international – not De Gea – was the world's best.
Asked if he had worked with or come up against a better shot-stopper than De Gea, Mourinho said: "Yes. Romero.
"Because he plays and my goalkeeper is always the best goalkeeper in the world. So now David is the third best.
"Romero is number one, Joel number two and David is the third best."
However, Mourinho still lauded the form of De Gea, who continues to shine at Old Trafford.
Summing up the Spaniard's season, the Portuguese tactician said: "Very good. Very, very good.
"All season very good."
