Ioannou joined Manchester United youth academy at the age of 11. He played at the Marveld Tournament with the under-15 team in June 2010 held at Netherlands. This was followed by his participation in Manchester United Premier Cup. His form earned him a two-year scholarship in June 2012. But it is also reported that Manchester United was reluctant to give him a full-time contract. He made his debut in Old Trafford against Charlton Athletic in FA Youth Cup aged 16. While playing in Milk Cup, he was injured which drove him out of action for most of the 2012-2013 season. In his last match for the reserves, he captained his team against Tottenham Hotspur. He also appeared in three 2013-14 UEFA Youth League group stage matches with Manchester United U19 team.
After being released by Manchester United, he signed a three-year contract with APOEL on 24 April 2014. On joining the club, Ioannou commented: "My main aim is to win trophies of course, but obviously I need to start playing. APOEL play in big competitions - Champions League and Europa League - so hopefully I can get a few games."
He made his official debut against Finnish club HJK Helsinki on 30 July 2014, in APOEL's 2-2 away draw for the third qualifying round of the UEFA Champions League. On 5 November 2014, aged 18, he made his first UEFA Champions League group stage appearance, playing the full 90 minutes in APOEL's 0-1 defeat against Paris Saint-Germain at Parc des Princes. In his first season at APOEL, Ioannou appeared only in seven matches in all competitions, but he managed to win the double, as his team won both the Cypriot championship and the cup.
On 3 June 2016, Ioannou signed a three-year contract extension until 31 May 2019, but a few months later, on 13 March 2017, he signed a further two-year contract extension with APOEL, running until 31 May 2021. Following his successful 2016-17 season with APOEL, Ioannou awarded the "Young Player of the season" award by Cyprus Football Association.
Being an English-Cypriot, Ioannou is eligible to represent the national teams of both the countries. In 2012, he had been capped by Cyprus U19. He made his Cyprus U21 debut on 5 September 2014, coming on as a 70th-minute substitute in a UEFA European U-21 Championship qualifying match against Belgium.
He received his first senior Cyprus national team call-up at the age of 18, being an unused substitute for Cyprus in the friendly match against Japan on 27 May 2014. He made his debut for Cyprus in 2017.
