That’s the view of sporting director Monchi, widely regarded as Europe’s best talent spotter.
Former Manchester City man Lopes was snapped up for around £23million in the summer from AS Monaco, but has managed just 11 minutes in La Liga so far this season.
But Monchi is refusing to brand Lopes a flop, just yet.
“If I have to be upset that Rony Lopes does not play, it would be with me, not with the coach,” he said.
“It’s too early to say I was wrong. If they don’t work in the end, the only culprit is me. I’m not looking for an excuse.”
