The Dutchman completed his transfer to West Ham after passing a medical on Thursday evening.
The 39 year old, whose contract at Manchester United was up at the end of the month, has chosen the Hammers ahead of Coventry City, who were also keen to sign him and made him an offer.
With Craig Forrest, Shaka Hislop, and Sven Andersson leaving in the summer, the need for back-up to David James was of paramount importance although the club does, of course, have young keepers Steve Bywater and David Forde on the books.
"I think he will be good for the club," says Ludo, "and it was Glenn's choice - he is a very experienced goalkeeper, which I think is important us.
"That is what we need now, as David James is the only other keeper with that experience, so it is great for the young goalkeepers who can learn from him - it is brilliant signing.
As for the young keepers David Forde and Steve Bywater, Ludo feels Raimond's arrival will benefit them as well.
"They just need games," he says, "which is why we need an older goalkeeper for next season, so that the young ones can go on loan to let them play - that is important for them."
And his views on THAT goal scored by Brazil?
"I think it was quite a shame, but it can happen to anyone," says Ludo. "When I have watched the World Cup games the ball has really been moving everywhere.
"Only David knows what was going on, but I think Ronaldinho meant it, that maybe he saw David a little bit off his line and struck it very well.
"It was very clever."
Raimond, incidentally, has signed an initial one year deal with a further year's option.
