Kilmarnock had been quiet in the transfer window, but that all changed on Wednesday night.
The Rugby Park side announced the return of Youssouf Mulumbu on loan from Celtic for the rest of the season.
The midfielder had been one of the star men for Killie under Steve Clarke last season.
But he left the club in the summer after his contract ran out.
He joined Celtic in August but couldn’t hold down a place in the first-team and now he has returned to Rugby Park.
The move to resign Mulumbu could well be one which makes a huge difference in Kilmarnock’s aim to win the Scottish Premiership title.
When he was at Rugby Park first time around, he was trying to help the Ayrshire side stay in the Scottish Premiership.
Now it is a completely different story, and he will be trying to help them win the title.
His guile, composure and experience will be vital for a team that doesn’t have many players who have experienced playing in big games.
That isn’t an accusation you can level at Mulumbu, who has played in the English Premiership.
Killie still have a bit to do if they want to win the league, as they currently sit six points behind leaders Celtic.
But the addition of a player who has been such a success before can only be a good thing for the club and the support.
