The Independent says the Irishman has been watched by Chelsea since Grant took over and is considered a bright enough prospect to be worth investing in over the next year.
The 24-year-old fits the template for players that Grant wants. Doyle is relatively young but proven in the Premier League. The club are also keen to bring in British and Irish players in the long term. Doyle signed a new deal this time last year that will keep him at Reading until 2010; as ever, Chelsea would be confident of meeting a transfer fee of around £8m.
