Saddlers boss Jon Whitney says he is pleased with his business in the January transfer window.
The Saddlers brought in five players during the month, including three on deadline day.
Midfielder George Dobson was first through the door, arriving on a two-and-a-half-year contract after leaving Dutch club Sparta Rotterdam.
Justin Shaibu joined on loan from Brentford on Monday, with Krystian Bielik, Jack Fitzwater and Julien Ngoy all signing on loan – from Arsenal, West Brom and Stoke respectively – on deadline day.
Commenting on this week’s transfer activity, Whitney said: “The lads who we’ve got in are ones we’d gone for in previous windows but hadn’t been available.
“They are going to bring added strength and quality to the group, which has already got a lot of quality in it. But you could see at Blackburn that we needed reinforcements.
“Defensively, we’ve got Krystian Bielik, who I think is going to be a really influential, top player – an Arsenal player.
“I spoke to the staff at Arsenal and Birmingham, who had him on loan last year, and I didn’t think we’d get him as I thought he’d go higher.
“He’s a full international and will be a big plus for us.
“In addition to that we’ve got Jack Fitzwater from West Brom. He’s been out to League Two for experience and his attitude is fantastic. It was good to increase our relationship with West Brom as well.
“In the forward line, we’ve got Justin Shaibu in. Our connections with Dean [Smith] and Richard [O’Kelly] helped get him in.
“He’s got raw pace, as has Julian Ngoy, who has played in the Premier League.
“He’s an international with Belgium and has undoubted ability. It’s a chance for him to cement a place and get match minutes in League One.
“I’m happy with the additions and hopefully they can help us kick on with the lads we’ve already got.”
