The on-loan midfielder told the club's website: "I don't think our confidence has been knocked, we know what we we're capable of and we just need to perform and work hard in training and do the business on Sunday.
"The determination and aim is to come out fighting against Tottenham, and everyone pulling together as a team to get a result.
"The fans have been great with me since I joined. When you're not scoring goals and not winning games they've got a right to be frustrated. We're paid to turn that around and make sure goals and wins come again. Hopefully we can repay them on Sunday."
