The former Baggies boss needs just one point to secure promotion from a possible nine.
Last night saw Real Betis take on Racing Santander in the Spanish Segunda Liga, with the Seville based side emerging the victors.
They claimed a 4-2 victory courtesy of goals from Bruno Gonzalez, Jorge Molina and a brace from Ruben Castro.
It was their third win in a row and the side remain unbeaten in their last nine outings.
When West Brom appointed Mel it was a decision met with shock by most fans. The popular Steve Clarke was shoved aside for the Spaniard in January 2014 on an 18-month deal.
Mel however was not a hit at the club, who he narrowly guided to Premier League safety. He left the club by mutual consent in May of last year and in December returned to Betis.
He has since gone on to be a huge hit with the Los Verdiblancos fans once again.
Since taking back over he has lost just one game out of a possible 22 and is now set to take Betis back to La Liga.
There are just three games left in the competition and they need just one point from a possible nine to secure promotion.
It may not have worked for Mel at West Brom, but he certainly has a place he can call home at the Estadio Benito Villamarin.
