Agustien revealed he tipped off his agent about Swanseaâ€™s search for a new keeper following the departure of Dorus de Vries after the clubâ€™s play-off promotion.
â€śMe and Michel have the same agent so I mentioned it to him when Swansea were looking for a goalkeeper because we knew a good one!â€ť Agustien told the Western Mail.
â€śAnd Brendan (Rodgers) asked me about keepers in Holland and I mentioned about Michel so itâ€™s great to see him here.
â€śI donâ€™t know if I helped, but Michel doesnâ€™t have to thank me, he should only be congratulating himself because he has done so well. I always knew he could do well and show how good he was in Holland in the Premier League, but heâ€™s been unbelievable."
