Mark Molesley said Tyler Cordner’s arrival brings further competition for places in the squad.
The 22-year-old centre back signed on loan from AFC Bournemouth until the end of the season earlier today.
And Molesley is looking forward to working with Cordner once again having coached him in the U21s at The Cherries.
"Tyler is no stranger to me and I know what I’m getting there,” said Molesley.
"He’s a centre half who is 6ft 4, both footed, good in the air, technically very good and they are hard to come by.
"We are trying to have the foresight of making sure we are at our strongest after this transfer window closes.
"Tyler gives us competition for places, he gives us more options and also sometimes players have had to play when they’re not quite ready this season, and we don’t want to be in that position.
"He’s got huge potential and all the attributes to be a really commanding, big, quality centre half.
"We’re going to be working really hard with him to realise that potential.”
Blues continue to be on the lookout for further signings, Molesley added, but the search for the ‘right’ additions is not a straight forward process.
"Yes definitely,” said Molesley when asked if he still on the lookout for signings.
"We’re aware of where we want to strengthen and we want to add quality to this group, not quantity.
"We want to get the right ones and sometimes the right ones and what we want aren’t always the easiest to find.
"Sometimes you’ve got to be patient, sometimes by being patient you don’t want to miss out on other ones, so it is a game of chess.
"A lot of things go into it but we are working tirelessly on and off the pitch.
"The Chairman is being fully supportive of everything we want to do and hopefully we will get the right people in to further enhance this group.
"We don’t want to be like we were at the start of the season, sort of under-resourced by missing our key players.
"We are looking for the right one or two to come in.”
