Arsenal are one of a number of Premier League clubs in the race to sign Getafe defender Djene Dakonam.
Dakonam, 28, was linked with the Gunners last summer but remained with the La Liga outfit, and earned his place in the Team of the Year for the second successive campaign.
He has impressed again this term and has attracted interest from the Premier League, with Arsenal , Tottenham , Everton , Bournemouth and Crystal Palace thought to be keen.
The Sun reports Monaco have already made a bid of around £13m, which was rejected by Getafe as they value him at closer to £22m.
Arsenal are eager to bring in defensive reinforcements this month with Calum Chambers set to sit out the rest of the campaign through injury.
