Salford City have signed Kylian Kouassi and Francis Okoronkwo on season-long loans as well as former Portsmouth defender Haji Mnoga and ex-Lincoln forward Hakeem Adelakun.
Kouassi, 21, made 24 appearances for Blackpool last season and scored five goals before his campaign ended early because of injury.
Okoronkwo, 19, joins from Everton, having turned out at youth level for the Premier League club.
Tanzania international Mnoga, 22, joins the Ammies on a one-year deal after leaving Portsmouth earlier in the summer.
Adelakun, 28, left Lincoln in May after spending the second half of last season on loan at Doncaster.
“I’m a striker that can come in and score goals, I’m hard-working and bring energy to the side,” Kouassi said.
“I spoke to the gaffer [interim Blackpool head coach Richard Keogh], we had a few chats about where he wanted to be at the end of the season and that attracted me to come here.
Mnoga told the club website: “It feels really, really good. It’s been a long window so I’m happy to get this over the line now and I’m really excited to get going,”
Okoronkwo added: “I’m not just a big striker, I like to get on the ball, I like to get other people involved. I’m not just going to score goals I’m going to try and assist, I’m going to try and play for the team, obviously graft and see where it gets us.”
