Premiership: Chelsea tie up four youngsters

Chelsea have tied four of their most promising youngsters into long-term contracts.

Leon Knight, 18, who spent last season on loan at QPR, has signed until 2005, while Scotland under-21 defender Warren Cummings is tied until 2004.

Both have joined Claudio Ranieri's first team squad for their two-week pre-season trip to Italy.

Sam Parkin, 20, and Robert Wolleaston, 21, have agreed to remain with the Stamford Bridge outfit for another two years, but both will start the new campaign on loan at Northampton.
