Despite there being less than four days to go in the window, Gourlay is adamant that Chelsea will continue to look for possible transfers.
"It's a very good signing for the club," Gourlay told Sky Sports News.
"We have always said we are always looking to strengthen, but it's all about the right players being available at the right time.
"Samuel was available and I think he just adds some experience to the players we already have around us."
Chelsea have been linked with a move for Manchester United striker Wayne Rooney.
