Swansea, having enjoyed an initial boost following the appointment of Paul Clement as manager, are in need of a fresh lift after three games without a win.
The Welsh side’s failure to beat second-bottom Middlesbrough at home last weekend was a particular disappointment and left the club one place and one point above the bottom three.
But Swansea centre-back Alfie Mawson insisted a goalless draw with Middlesbrough had not dented the squad’s self-belief.
“We go again on Wednesday against Tottenham and with a big crowd behind us hopefully we can get the result we want,” he said.
“Confidence is still very high going into Wednesday’s game. The squad is fit and ready for the challenge.
“The belief is fully there that we will stay up. I am very confident in us.”
Clement hopes to welcome back striker Fernando Llorente who missed the Boro game with an ankle injury.
The manager said: “We missed Fernando –- he is a big focal point for us. He has an ankle issue that I am hoping will not keep him out for long.
“Wednesday is achievable, although he is still a doubt for that game.
“He has a chance, but we are very much looking at him day to day.”
