MARKUS Olsson last night completed a move to Derby County that could make Blackburn Rovers £1m – and he is set to be followed out of the Ewood Park exit door by Fode Koita.

It is understood that Rovers are guaranteed to receive around £750,000 from the big-spending Rams for their reigning player of the year Olsson.

But the fee for the Sweden international left-back, who had just six months remaining on his contract, could yet hit seven figures.

And Rovers are also set to make a quick profit on Koita who has headed to Turkey to complete a proposed switch to Kasimpasa.

The striker went close to signing for Kasimpasa’s Turkish top-flight rivals Sivasspor before his arrival at Ewood in July.

But Koita has failed to settle and struggled for fitness since his free transfer move from Ligue 1 side Caen.

It is understood that Rovers stand to make more than £200,000 on the former France Under-21 international.

Paul Lambert will now concentrate on bolstering his squad before the transfer window closes at 11pm on Monday.

And, speaking after Saturday’s 1-1 draw at Charlton Athletic, the Rovers boss admitted he will ask owners Venky’s if he will be able to use the money generated by sales to buy new players.

“I need to have a word with the powers that be to see what is going to happen with the money,” said Lambert, who has dealt mainly in the free transfer and loan market this month.

“There will be a decision to make and you have to respect the decision they make but hopefully it (the transfer fees) will come back in to us.”

Lambert has put a left-back, to act as competition for Tommy Spurr, to the top of his shortlist along with a creative midfielder.

Olsson was set to become a free agent in the summer and, after talks over a new deal hit deadlock, Rovers decided to cash in.

The 27-year-old, who was subject to late interest from QPR, has signed a three-and-a-half year deal with Derby.

“I had been at Blackburn for a while but it felt right that now was the point to experience something new in my career,” said Olsson, who made 114 appearances for Rovers, scoring one goal, after his free transfer switch from Halmstads BK in January 2012.

“So when I heard about Derby’s interest I was very happy and it’s something that appealed to me straight away. This was my first choice.”

Rams boss Paul Clement has revealed that former Rovers defender and first-team coach Craig Short advised him to sign Olsson.

“We’re delighted to welcome Markus Olsson on board; he strengthens the options for us at left-back,” said Clement, who had a spell as Rovers’ assistant manager before Olsson’s arrival.

“He is a player that we have been monitoring for some time and I am very pleased that we have now completed the deal.

“Markus was Blackburn’s player of the season last year so that shows how highly rated he was there and Craig Short, who I know well, has provided a glowing reference after working with him at Ewood Park.”

Lambert said: “It is a really good deal for the club.

“He was out of contract in the summer and could have walked away for nothing so it was important that we acted in the club’s best interests.”
