Ramos disagreed with Zokora's red card against Manchester City

Speaking through an interpreter, Ramos said: "It is a positive result. Given the circumstances, it has to be the best performance since I took charge.

"We were away from home against a team who are high in the league and on a good run of form at home.

"Not only that, we were a man down from the 20th minute yet still got through."

Ramos disagreed with Zokora's sending off for a lunge at Elano and played down striker Jermain Defoe's reaction at being substituted when Spurs reorganised.

"It wasn't a sending-off, not in a game like this," Ramos said. "A cup tie generates a heated atmosphere, and the referee has to be a bit more flexible. It was unfair.

"But Jermain understands the change was tactical. He knows we had to bring on an extra defender."

City manager Sven-Goran Eriksson was left to rue his side's inability to turn possession into goals as they pushed forward against Tottenham's 10 men.

"The players and the fans, like myself, are all very disappointed," Eriksson said.

"We thought being at home we had a good chance of reaching the semi-finals, but Tottenham started very well. �
