West Ham have confirmed the signing of defender Tyrone Mears from Preston North End for a fee that could rise to almost £2million.
The 23-year-old right-back has agreed a four-year deal with the Barclays Premiership side for an initial fee of £1million to become the Hammers' second signing in quick succession after Carlton Cole moved across London from Chelsea.
The highly-rated defender could cost up to £1.9million depending on appearances and future recognition at international level with England.
The Hammers had turned their attention to the Stockport-born player after attempts to sign Luke Young from Charlton fell through over the weekend - the Addicks had themselves identified Mears as a potential replacement for the England full-back.
Preston revealed they had turned down two bids from Charlton before agreeing a fee with West Ham manager Alan Pardew.
Mears began his career as a trainee at Manchester City but made just one first-team appearance when he came on as a substitute against Nottingham Forest in March 2002.
He then moved on to the Lilywhites for £200,000 in July 2002 but the following two seasons were disrupted by injury before he returned to full fitness for the 2005/06 campaign and was an integral part of the side which lost out to Leeds in the play-offs.
