Demba Ba declared there was no comparison between Chelsea and Newcastle - or West Ham - after completing his move to the European champions.

The Blues announced the signing of Ba on a three-and-half-year contract on Friday morning after activating the £7million release clause in his Magpies contract, the value of which had controversially become public ahead of the transfer window.

It is the second time Ba has exploited such a clause since moving to English football, having been allowed to leave West Ham following their 2011 Barclays Premier League relegation. The Senegal star told the club's official website, www.chelseafc.com: "This club is at another level - it isn't West Ham or Newcastle."
