Deportivo La Coruna boss Jose Luis Oltra believes his side's match with Real Betis on Sunday is of 'the highest difficulty'.
The Verdiblancos travel to Estadio Riazor this weekend looking for their third win in a row, and the 43-year-old has claimed that Pepe Mel's team will pose a tough test.
“It is an important game of the highest difficulty,” he told a Press conference. “They are a team that has spent three years with the same Coach.
“The first season they got promoted, the second season was a consolidation and now they are tied for fifth in the table and have just beaten Real Madrid.
“We are at home though, and we must compete well to get the three points. We have emerged stronger from the last two games [draws with Athletic Bilbao and Real Mallorca] and we must take advantage.
“Those good feelings have to be transferred for the win, and if that happens, it could be a turning point.”
