Frank Lampard has suggested there is no guarantee that Chelsea will “switch on” next season.<br /><br />The caretaker boss, who has overseen a dreadful run of form to close out the campaign, suggested other Premier League clubs will also strengthen ahead of next season.<br /><br />“Everyone’s moving on and trying to do the same things,” Lampard said.<br /><br />“My experience of football is that if you switch it off, it’s not easy to switch it on, so that doesn’t become an overnight remedy.”
