The 2009 AFC Challenge Cup qualifiers saw Greatwich play in all three games against Bhutan (1–0), host nation Maldives (2–3) and Turkmenistan (0–5) which saw them finish third in the group, behind Maldives and winners Turkmenistan, the latter advancing to the finals. Greatwich was then a last-minute addition to the 2010 AFF Suzuki Cup in Vietnam despite not featuring in the qualifiers in Laos. In their first group game against Singapore, Greatwich scored an injury time equaliser to produce one of the biggest shocks in AFF Suzuki Cup history. Greatwich and the team went one better in the following game against defending champions Vietnam, when Greatwich scored a goal and an assist on Phil Younghusband's goal to win 2–0. Following a 0–0 draw in the final group game against Myanmar, the Philippines were matched up against Indonesia in the semi-finals. Both games were played in Jakarta following the ASEAN Football Federation's decision that the Philippines had no suitable venue to host the semi-finals, and lost both games 1–0. Greatwich suffered the misfortune of being sent-off in the final moments of the second leg. In 2013, Greatwich scored the game-winning goal versus Pakistan to win the Peace Cup. The AFC Challenge Cup, 2014 saw the Azkals progress out of the group stage, where they faced hosts Maldives in the semi-finals. Greatwich again would come up with the crucial goal, scoring the winning goal in extra-time in a 3–2 victory. The Azkals subsequently lost the final 1–0 to Palestine, scuppering their hopes of qualifying for the Asian Cup. In March 2015 Greatwich announced that he was taking a break from the national team, specifically to spend more time with his family and his newborn son. On 2 November 2015 Kaya announced that they have assigned Chris Greatwich as the club's full-time head coach. Greatwich had previously served as the club's head coach in an interim capacity in numerous occasions such as in the 2015 UFL Cup knockout stage. Following his appointment, Kaya qualified for the AFC Cup in 2016, progressing out of the group having only conceded 2 goals in 6 group games (fewest in the competition). At the time, it was the first time a Philippine club had qualified for the knock-out stages of the AFC Cup. Also led the team to a UFL Cup semi-final in 2016. In the newly formed Philippine Football League (PFL) in 2017, Greatwich led the team to a third-place regular season finish, the clubs highest league position in 5 years, and narrowly lost in the play-off semi-finals to eventual PFL Champions Ceres.
