The Former Arsenal man has let out his regrets for having left North London for Barcelona during his playing days.
Having joined Gunners from Stuttgart back in 2005, Hleb spent just three seasons at Emirates Stadium before leaving for Barcelona.
Although having been seen back then as one of the big moves, the Attacking Midfielder appears not to be happy to have left Arsenal.
The Belarus star made 130 appearances for Arsenal before joining Barcelona where he made just 36 appearances before been loaned out.
While with Arsenal, Hleb reached the Champions league Final with the squad but with Barcelona he won the UCL trophy, the La Liga and the Copa del Rey but has lamented on the move.
Sadly for Hleb also he had fallen out of favor despite the memorable first season at Camp Nou as he was loaned to Stuttgart, Wolfsburg and Birmingham before his contract was terminated by Mutual agreement.
“Many years later and I still think about it,” Hleb said on Arsenal’s In Lockdown podcast.
“I don’t understand. To this day I still don’t understand what happened or why I made the decision.
“Of course, Barcelona in that moment was the best team in the world but I was really happy at Arsenal at the time. I had friends, I enjoyed the coach, I was playing for one of the best teams, the fans, the stadium, everything! The fantastic championship, the Premier League, everything!
“Why I left, I don’t understand. Barca, of course, were the best team at the time and everybody wants something to try but really I was 100 per cent happy at Arsenal.
“I cried when I talked to Arsene [Wenger]. We talked in the holiday before I left and he told me he wanted to keep me and I was important. I cried. I didn’t know what to do in that moment.
“Of course, Barca is a fantastic team. I won titles and everything but I didn’t play as much as I did at Arsenal. This is only my mistake because at the time, a lot of things happened in my private life. I started very nervously [at Barcelona]. Always aggressive. It was only my mistake.
“This is not a situation where Guardiola didn’t trust me or something like that. No, this is only my mistake. At Arsenal I was happy, you know? When you’re happy in the team, you need to stay.
“Of course [I still think about my career]. When you’re young you think you have so many years but it’s really like one moment. It’s really quick. My children now ask me about [my career] and you explain your emotions and it’s nice, it’s very nice.”
