Mainz boss Bo Svensson is concerned about losing Nottingham Forest target Moussa Niakhate.

The centre-back is emerging as a key option for the newly promoted Premier League club.

Manager Steve Cooper is eager to add the £10 million-rated defender.

"That's the downside of performing and performing well," Mainz boss Svensson told Goal.

"We know that we have clubs that have more money than us and will look at players that were doing well at Mainz because that's just natural.

"That's where we are in the food chain, so what we can do about it is we can prepare ourselves as well as possible, keep an eye out on players who could be interesting to replace Moussa or replace some of the other players just to strengthen our own team and be as well as prepared as we as we possibly can.

"It's too bad that we cannot go on with the same players year after year, but we're not the only team who have this challenge and it's also the normal way of things that you have to be able to adjust and think ahead, so we've been well prepared for things that would happen this summer.

"In the football world things are unpredictable. So sometimes you just have to accept things, sometimes some things you can plan for, and other things you have to be flexible and accept that you are where you are."
