"These games hurt you know," he told WHUTV. "I can only talk for myself but the last two games have hurt me and we have got to get it back. There is no better game to go into for me personally, with the rivalry that we have got, than Spurs on Sunday.
"Every game is tough in the Premiership but there is no better game to go into after these two bad defeats," he added. "Knowing the rivalry and everything this is where we are going to see who is going to step up to the plate."
Ferdinand is clear though that the team can still bounce back in the final ten games of the season and make inroads up the table.
"I can't say we are in a crisis. Everyone knows what a crisis is - which was last year - and we dug ourselves out of that. We have got to get back the feeling we had last year which helped us get out of that situation."
