Joseph Yobo says Everton boss Dave Moyes' new signings have lifted the quality within the squad.
The Nigeria international defender told evertonfc.com: "It's all about buying quality rather than quantity," said the Nigerian. "The manager knows what he is doing.
"We all want to see better players coming in. We are playing in Europe and we know it is going to be a tough season."
"Our squad is not the biggest and we have got a few injuries, to Vaughany and Tim," he said.
"But they will recover before too long and who knows what will happen before the start of the season?
"If we can sign one or two quality players, that would be great."
