Simo Valakari is "a happy man" after adding midfielders Josh Campbell and Joel Cotterill to his St Johnstone squad this week.
German forward Danny Schmidt has also been recruited and has obtained a work permit in time for Sunday's Scottish Premiership visit of Hibernian (15:00).
However, as Hibs are loan player Campbell's parent club, he will not feature at McDiarmid Park this weekend.
"I'm a happy man," Valakari told Saints TV.
"I was very happy to be able to get those two players. I was very happy with the squad and players we added. Joel and Josh were on our radar at the start of the window. Things don't always happen as fast as you wish but we were not in a rush.
"I was happy with what we had and I knew we would start the season well. We didn't just need to add numbers. We were in a good position to hold our nerve, focus and really go for those players we believed would really add something to our squad.
"I'm so happy they are here, they are both great characters and personalities and have football qualities that will really help our team."
