The 30-year-old moved to Elland Road shortly before the end of the January transfer window and has made an immediate impact.
United have taken six points from the three games that Bamba has played, the latest of which was Tuesday’s tremendous 2-0 win at Reading.
Redfearn is in no doubt that the former Leicester City defender, whose last game in England before joining Leeds was, coincidentally, at Elland Road in May 2012, has played a major part.
The Leeds head coach said: “Sol has been the type of player we have perhaps been crying out for. He has got leadership and he has galvanised the back four. He was outstanding again the other night.
“He has been massively important and instrumental in the run. He has experience, he has given us a physical presence that we were maybe lacking. But along with that height and strength, he can play.
“He understands his position and he’s been a fantastic addition. The transfer deadline was an important time for us in the sense of keeping our better players. The club showed a willingness to do that.”
Bamba will again be at the heart of the United defence tomorrow for the clash with Millwall.
United will be buoyed by a run of six games since the turn of the year that have yielded 11 points. It is a return that has helped take Redfearn’s men clear of trouble, but the head coach realises no one can rest on their laurels, especially with the Lions sitting just five points behind the Yorkshire club going into tomorrow’s game.
With that in mind, Redfearn is keen to add at least one new face during the emergency loan window and former Scunthorpe United man Martyn Woolford is believed to be on the radar.
He said: “We are definitely looking. I have mentioned certain players and we know the areas we are targeting.
“It is not a secret. But it is about getting the right ones in.
“If you can’t, you might as well persevere with the ones you have got.”
On Woolford, he added: “He has got Championship experience, he scores goals and he gives you physical presence on the left. He gives you that balance and he is the type of player we are looking for.”
