The Southampton boss has no problem with the referee taking charge of the clash with West Ham despite the club lodging a complaint over alleged comments made towards Adam Lallana
Clattenburg has not officiated a match involving the south coast club since the club lodged a complaint against him following December's 2-1 defeat at Everton.
The FA decided against any action despite the south-coast club being angered by comments Clattenburg allegedly made to captain Adam Lallana during that fixture, and Saturday's encounter against Sam Allardyce's side marks the first time the referee will take charge of a Saints match since then.
The Saints are 11/8 to beat West Ham at Upton Park on Saturday
"I'm not worried at all about that. If I'm completely honest I'm happy [Clattenburg] is refereeing for us," he said. "What happened in the past stays in the past, the fact he's refereeing means the situation that was taken out of context in the past stays in the past.
"It's clear both parties made mistakes. Refereeing is a tough profession, Southampton as a team are going to help as much as possible to make his job as easy as possible. Human errors can happen, we just want to help him do the best job he can.
On Lallana, he added: "Adam is a player and a person that only thinks about football. He doesn't think about other things. I'm sure he has a bitter taste for what happened in the past, but it's in the past.
"He, and the club as well, want to normalise the situation. We are a friendly club, a friendly team, we want to show that and not have problems with referees."
Pochettino could be handed a double boost ahead of the visit to Upton Park, with centre-back Dejan Lovren and forward Gaston Ramirez both in line to return.
The duo have not featured for Southampton since simultaneously leaving the field on a stretcher in the 2-2 draw at Sunderland on January 18 with ankle injuries.
However, defender Jos Hooiveld will not feature due to an eye injury.
