The LA Galaxy new boy's professionalism came under question during his disappointing four-year stint at White Hart Lane.
Speaking ahead of the Galaxy’s home game against New York City FC tonight, when he is expected to partner club captain and former Spurs teammate Robbie Keane up top, the Mexico international told ESPN FC: “I have a lot more experience now. I’m older and I have learned a lot of things in football since.
“I feel more mature now, and playing with him [Keane] makes it easy as well because he’s one of the top players [in MLS].
“I can just pass the ball to him – or to Steven [Gerrard] – so I’m very happy to play with him again. He’s a very intelligent player, who always finds the perfect spots.”
Dos Santos’ lauded potential saw him break into the Barcelona first-team as a teenager but his career would soon start to unravel following a high-profile move to Tottenham in June 2008.
The promising attacker ended up featuring just 33 times for the club over the next four seasons, while playing on loan at Ipswich Town, Galatasaray and Racing Santander, respectively, before returning to Spain in August 2012 to join Real Mallorca after failing to adapt to English football.
Ex-Spurs boss Harry Redknapp also claimed that the now-26-year-old was not disciplined enough and a little too fond of the London nightlife but Keane, who mentored his fellow attacker during their time together at White Hart Lane, has since insisted that things were more complicated than that.
“He was only [19 when he arrived at Tottenham], just a kid,” Keane told MLSSoccer.com earlier this month. “He didn't get the opportunity that I felt he should have at times and, obviously, he did as well, but that's the way it goes. I think things like that can sometimes help players, help them mentally.
“Look at the season he had last year [at Villarreal]. He had, what, 16 goals? . He was one of the best players in [La Liga]. He's a fantastic player; we're lucky to have him.”
Joining the Galaxy from La Liga outfit Villarreal last month as their third Designated Player after Keane and fellow summer signing Steven Gerrard, Dos Santos has since made an impressive start to life in the States, racking up two goals and four assists in his first four games.
With his fifth appearance set to come against NYCFC tonight, the likes of David Villa, Andrea Pirlo and Frank Lampard could be in for a tough time if the skilful No. 10 is in the same kind of form as recent weeks.
