LONDON (AP) — Chelsea's bid to sign Manchester United striker Wayne Rooney has been rejected by the English Premier League champion.

The 27-year-old Rooney has been pushing for a move since expressing his frustration to the club about his lack of playing time at the end of last season.

Alex Ferguson and David Moyes, who succeeded his fellow Scot as manager in May, have insisted Rooney was not available.

But Chelsea maintained its pursuit of the England striker, culminating in a formal bid submitted to its Premier League rival. The London club confirmed in a statement that it made a written offer for Rooney.
