The 27-year-old also urged the club, which is yet to make a summer signing, to buy big-name players - and "not players you have to Google".
"When you have young players with a good understanding and another year of experience, they have to be better, so I don't think it will be a problem for them because they have the same manager, the same staff, the same players and more experience in the Premier League, so they will be even more risky".
"Having had time to consider my actions, I acknowledge now that the timing and manner of what I said was ill-judged".
Tottenham have seen their lack of transfer activity questioned from inside their own camp of late, with England global Danny Rose admitting that he expected more from the club.
Tottenham manager Mauricio Pochettino concedes he was probably the subject of a few Google searches when he first arrived in the Premier League. Rose said in a statement released through agency Base Soccer.
"I haven't spoken to him today because he's injured and is recovering from his problems".
"We want to strengthen in different areas, in all areas". I'm sure I'll see him tomorrow. The players were very calm and we were calm. "I forgive him and now we move on".

The transfer window closes on August 31 and Pochettino looks to settle Tottenham fans' concerns with his insistence that the club has a trend of spending late in the month.
"Last summer he signed a five-year contract", the Argentinian said.
But Pochettino was at pains to stress that the matter was not resolved, with Rose's inflammatory comments not indicative of a wider problem within the dressing room.
"Of course (he has a future)". Nothing has changed in my vision or perception of him.
While most players are typically linked with United, whether they are actually looking to move clubs or not, a move for Rose would not be within United's best interests.
Wenger believes any Spurs anxiety about playing at the ground is simply psychological but he does feel they will struggle to generate capacity crowds of 90,000 fans throughout the coming campaign.
If Spurs want to continue on their path to victory in both the Premier League and on the European stage then this season is crucial, they must still at least finish in the top four, get out of the Champions League group stage and aim to win one of the domestic cups.
