Tottenham boss Mauricio Pochettino feels Gary Neville has taken on a big challenge at Valencia.
Pochettino says former Manchester United captain Neville has taken on a difficult job at Valencia, but wishes him all the best.
Pochettino enjoys a good relationship with Neville, who spent time at Tottenham's training ground last season and recently described the Argentine as his "favourite coach in the Premier League".
"I sent a text to him to wish him all the best because he is my colleague," Pochettino said. "He is a brilliant man and I wish him all the best. It's a difficult job to take Valencia now."
