Altman joined the youth squad of Maccabi Tel Aviv at the age of 11.[citation needed] His good performances attracted interest from Premier League clubs[2] and earned him a move to Fulham in 2011.[3]
On 27 June 2013, Altman was loaned back to Maccabi Tel Aviv.[4] On 17 July 2013, Altman made his first ever official appearance with the senior team of Maccabi in an important match against Győri ETO FC in the 2013–14 UEFA Champions League qualifying rounds. On 20 October 2013, he made his league debut in a 1–0 victory against Ironi Ramat Hasharon.[5]
On 19 June 2015, he signed with Hapoel Tel Aviv for five years.
On 28 June 2017, Altman signed a three-year contract with Panathinaikos from Hapoel Tel Aviv for a transfer fee of approximately €150,000.[6] On 17 September 2017, he scored with a header the only goal in a 1–0 home win against Apollon Smyrni.[7]
The Israeli youth international was brought to the club as a virtual unknown from Hapoel Tel Aviv for a fee in the region of €150,000. This highlights the severe financial constraints impacting Marinos Ouzounidis. The attacking midfielder, however, has done relatively well barring an injury that kept him out for some time. His two goals in the first half of the season came in a home win against Apollon Smyrni and in a draw away against Xanthi.
On 4 March 2018, Altman suffered cruciate ligament injury during the Panathinaikos' away derby clash against Olympiacos which resulted in him missing the remainder of 2017-18 season.[8] His return was initially penciled in for September or October 2018, but it got delayed as he returned to his native Israel for further treatment. On 21 January 2019, after a very difficult period for the midfielder marred by injury (313 days to be exact) he returned to the squad in a 1–0 away loss against Lamia. On 16 February 2019, a month after his return he scored after a great pass from captain Dimitris Kourbelis which Altman chested the ball down superbly before firing a powerful shot beyond Nikos Papadopoulos from the edge of the penalty area, sealing a 1–0 home win game against Asteras Tripoli.[9]
