The Baggies are still waiting for their first victory under Steve Clarke's successor after Sunday's 1-1 draw with Liverpool, but the Spaniard insists the results will come
The Hawthorns outfit are still awaiting their first win under Mel, with 1-1 home draws against Everton and Liverpool sandwiching Wednesday's 4-3 defeat at Aston Villa.
But Mel remains upbeat, insisting he had seen positive signs in his short time at the club.
"I think two weeks is good work for us," he said.
"I think this week will be even better for us in getting the message across. We have good work to do at the training ground.
"It was very important not to lose yesterday [Sunday] because the players need to believe.
"To lose two games would be no good for us so we had to get something from the Liverpool game.
"The Premier League table is very compact. For us it was important that we work day to day, week to week and we need to make sure West Bromwich remains in the Premier League."
