Former Chelsea star Gus Poyet is backing their move for departing PSG captain Thiago Silva.
The 35 year-old defender is expected to ink terms with Chelsea this week.
"I think he is top," Poyet told Sky Sports. "I know he's 35, I think you need experience.
"The teams that, as a club they have a strategy to go with young people, they (also) try to keep a line of experience, the goal keeper, one of the centre halves, one of the midfielders and the striker.
"They don't go young everywhere, so that helps you to make the others more comfortable."
