A source told The Sun: "All the girls think he's a real ladies' man. But they're soon disappointed when it turns out he's not interested in women.
"He'll ruffle a few feathers and Christian and Syed's relationship will be tested."
Fans could be left to wonder whether Christian and Syed's relationship will break down because of Danny.
An EastEnders spokesperson refused to confirm or deny the rumour, telling Digital Spy: "It's fair to say that Danny is going to cause a few problems for the residents of Walford but viewers will have to tune in and see for themselves as we don't want to spoil the surprise!"
Details of mischievous city banker Danny first emerged at the beginning of the month.
Ex-Footballers' Wives star Lucy has signed up for an initial three months with the BBC soap.
