Gordon Strachan's men have not been getting great results themselves, having lost half of their 12 home league fixtures so far leaving them 19 points adrift of Newcastle in top spot.
Tate told the Swansea Evening News: "Middlesbrough were very good when they came to our place. But we are a completely different side now compared to what we were then.
"We were a team in transition when we played them at home and I think you could tell. But we have managed to put a good run together and we have come a long way since August."
