Chelsea are expected to test Manchester United’s resolve over Wayne Rooney with a vastly improved offer in the coming days, Metro reports.

According to reports, the Blues are preparing a huge £40m bid for the wantaway striker – £13m more than the sum rejected by United last month..

Rooney emerged as Chelsea’s top transfer target this summer, having reportedly handed in a transfer request to Sir Alex Ferguson at the tail end of last season.

But United boss David Moyes has insisted time and again he has no intention of selling the former Everton youngster, despite the fact Robin van Persie looks likely to remain the no.1 frontman at Old Trafford.
