Tenerife B

I was looking at how relegation works in Segunda B as with one round to go the B team are at present in relegation. The four teams at the bottom are relegated and then the next team in 16th position has to play play offs.
Tenerife B lost at the weekend against Cacereño 4-0. We play Sporting B for the last round of the league and need to win and that all the other teams around us lose.
