The 25-year-old has been at The Valley for 18 months and has impressed hugely since moving from Sheffield Wednesday.

The Algerian international is now attracting interest from a host of clubs, but Betis are the first to show their intent.

It is believed Betis lodged a bid of 2million euros (£1.5million) with Charlton last week, but the Addicks have already rejected that.

Now Betis are ready to come back for a renewed offer, although there could soon be further interest from elsewhere.

Wigan are also said to be taking a keen interest and could very well join the bidding.

Bougherra has three years left on his current contract and is more than happy with life in south London.

The talented centre-back is now set for talks with Charlton, who could very well look to hand him an improved contract in a bid to keep him.
