Rose apologised for his comments on Friday, releasing a statement that was timed before Mauricio Pochettino's press conference with the player offering contrition for what he deemed "ill-judged" words.
But Pochettino said he himself had been considered an unknown when he arrived at Southampton in 2013 and also cited the rises of Spurs pair Eric Dier and Dele Alli and Chelsea's N'Golo Kante.
"That is not a joke".
Gayle missed the final two friendlies of pre-season due to these hamstring/confidence problems and only played 30 minutes of the third last one. Or Dele Alli who was in League One or Kante.
"If you remember four years ago, the people say, 'Who is Mauricio Pochettino?' I'm sure they used Google or Chrome!"
Daniel Levy is claimed to be in Amsterdam attempting to seal a deal for the 21-year-old Columbian who has two worldwide caps. "But it's ok - look now!"
"If you see the squad, it is obvious that we need a striker".
Pochettino, who was speaking at a news conference ahead of Sunday's Premier League opener at Newcastle, took the unusual step of answering numerous questions in Spanish, asking his assistant Jesus Perez to translate.
'Danny Rose is a fantastic player but he has been mishandled, whoever has advised him to do that is ridiculous. No, no, no. I'm exhausted. "It was like, 'Wow, how did he do that?' I mean signings like that are what we need - that's just my opinion".
"Sometimes we will do it and sometimes, we will not do it, but we have to be sure that every single game, the players give everything and myself and my staff will do the same".
"I'm not anxious", he said.
"I've never seen him be upset about the (lack of) signings either around the players or around the training ground. With the players we have we can compete in a very good way".
"He obviously would not want that, because you don't want to be going into a season when the whole team is down". If I feel that why can I be nervous? You reflect upon people's character by what they do and how they behave. "I have no doubt about the team". I leave that to the chairman.
