The Frenchman has emerged as the top priority target for Arsenal and Tottenham, but the Argentine refused to comment on the possibility of reuniting with his former player
Mauricio Pochettino is remaining tight-lipped on reports suggesting that Tottenham are planning to swoop for Southampton's Morgan Schneiderlin.
Since Pochettino's departure from St Mary's a number of key players have left the Saints - including Luke Shaw, Adam Lallana and Rickie Lambert - with Dejan Lovren set to follow with a €25 million move to Liverpool.
Tottenham, meanwhile, have already recruited Swansea City pair Michel Vorm and Ben Davies, with Gylfi Sigurdsson heading to the Liberty Stadium as part of the deal.
Earlier this week Goal revealed Schneiderlin is now the No.1 transfer target for both Arsenal and Tottenham but, while he admits he would like further reinforcements, Pochettino refused to shed any light on the speculation.
"We're trying to improve the squad but I never speak about players from other clubs," he told reporters. "I have respect. I'm just focused on my team."
Pochettino was speaking after Tottenham defeated Chicago Fire 2-0 on Saturday, as the club ended their pre-season tour of the United States unbeaten.
And the Argentine was happy with the progress his side made during their visit to America.
"I'm very pleased for the players because we've finished with a good win, a clean sheet and that's a boost for the confidence," he added.
"It was difficult in the humidity but well done to the players, it was a good game out there. I'm happy for all of them. I thought we played well.
"We've worked hard on this tour and congratulations to the players, staff and the supporters, they've been fantastic."
