It has to be said that of those three defenders it would be Umtiti that would be my prefered option but as with the Rugani and Upamecano situations it is a case of money and whether it is a loan deal or permanent deal.
Football fans were rocked with some unusual news on early Tuesday, as reports surfaced suggesting that Barcelona's Brazilian star Coutinho, now the 5th most expensive player of all-time, was on the verge of joining Arsenal on loan.
However, the Premier League club have told them that at the moment their focus is on securing a central defender.
"He's a splendid player, but we haven't talked about Coutinho at any time".
Emery is likely to start the Premier League season with Sokratis Papastathopoulos and Calum Chambers as a centre-back pairing at Newcastle on Sunday.
Martin Keown has played down Arsenal's chances of signing Philippe Coutinho from FC Barcelona before Thursday's deadline day.
It was first suggested that a move to Arsenal was a possibility.
L'Equipe had reported that Arsenal were in the race, but the Gunners themselves denied those claims.
But some rumours claim, the deal has collapsed because the Lilywhites were unable to meet the wage demands of the Brazilian.
Spurs are in talks with Barcelona to complete a deadline day beating swoop for Coutinho, with Mauricio Pochettino keen to welcome the former Liverpool player to north London.
