Watford winger Gerard Deulofeu has taken aim at new Barcelona coach Ronald Koeman.

The former Barcelona winger spent part of the 2016/17 Premier League season under the orders of Koeman at Everton but he feels he didn't learn much.

"I can tell you about Koeman from my personal experience, and I have very little to tell you about Koeman," he said on Cataluyna Radio.

"He provided me absolutely nothing.

"I wasn't happy, I asked to leave and I went to Milan.

"We'll see how he does at the Camp Nou."

Barcelona are going through a crisis, yet Deulofeu didn't seem too bothered.

"The truth is that Barcelona's [situation] does not bother me," he said.

"In fact, right now, I don't care."
