Frank Lampard won't leave Chelsea due to loyalty bonus?

Chelsea midfielder Frank Lampard has reportedly refused to be forced out of Stamford Bridge due to a loyalty bonus that he is owed at the end of his contract.

The Blues playmaker has been shunned from Andre Villas-Boas's side in recent months, with rumours surfacing linking the England international with a transfer away from the former Premier League champions.

Despite reported interest from French outfit Paris Saint-Germain, it is believed that Lampard doesn't want to miss out on a £1.5m loyalty bonus, according to the Daily Mail.

The bonus is due to be paid at the end of his current contract, which expires in the summer of 2013.

Concerns of unrest in the Chelsea camp have grown following Villas-Boas's decision to snub Lampard and full-back Ashley Cole for the Blues' 3-1 defeat to Napoli in the Champions League in midweek.
