St Mirren: Kyle McAllister & Calum Waters sign for Paisley side
St Mirren have re-signed midfielder Kyle McAllister on a three-year deal from Derby County and loaned left-back Calum Waters from Kilmarnock.
McAllister, 20, who left the club for Derby in January 2017, spent the second half of last term on loan in Paisley, scoring three times in 12 games.
Waters joins the Scottish Premiership club on a season-long loan.
"Everybody knows what Kyle adds. Technically he is fantastic and very creative," Goodwin said.
"He made a great impact last season and it's up to us to manage him properly and make sure he stays fit and becomes a regular for us."
Waters, meanwhile, played under Goodwin at Alloa Athletic but the 23-year-old has struggled for game time at Kilmarnock because of the form of Greg Taylor.
The deal has a clause which allows the Rugby Park club to recall him in January.
"Without putting too much pressure on him, he's very similar to young Taylor and I'm looking forward to getting him in the team," Goodwin added.
St Mirren have also confirmed that striker Cody Cooke will only be out for three months with a knee injury.
It had been feared that the Englishman would miss up to nine months after rupturing knee ligaments, but it has emerged that he does not need surgery.
"It's a huge relief for Cody," Goodwin said. "It turns out the ligament he has damaged is on the opposite side to the cruciate so it's not as serious as first feared."
