Former Spanish international Raul has warned Barcelona's Xavi that moving to Qatar would be a major shock to the system.
Xavi is widely expected to leave Barcelona at the end of the season and has been strongly linked with a move to Al Sadd – a club that Raul represented between 2012 and 2014.
The now New York Cosmos forward has said that on many occasions, "there was no-one in the stands in Qatar".
"I got used to playing at half-empty stadiums at Al Sadd," Raul told Panenka. "There was no-one in the stands in Qatar. The atmosphere in New York made me all of a sudden feel like I was back at the Santiago Bernabeu."
Raul, who faced Xavi many times during his time at Real Madrid, won the Qatar Stars League with Al Sadd in 2013.
