When Marcello Lippi took charge of China's troubled national team a little more than two years ago, hopes were high the World Cup-winning Italian could kick-start a long-overdue return to the upper tier of Asian football.
But, as the septuagenarian's tenure draws to a close at January's Asian Cup finals, the question is whether Lippi has made much of a difference at all.
While the former Juventus manager oversaw an upturn in fortunes in the early days of his reign, China go into the tournament in the midst of an indifferent run of form.

Kyrgyzstan will be making their first appearance at the Asian Cup finals having qualified for the tournament from a group that featured India, Macau and Myanmar.
The former Soviet Republic gained membership of the Asian Football Confederation in 1994 and lack experience at continental level.
They have enjoyed a mixed build-up, but talented performers such as Anton Zemlianukhin and Vitaly Lux enhance their hopes of a place in the knockout rounds.

Sven-Goran Eriksson's surprise appointment as manager made headlines around the world, and now the basketball-mad nation is hoping the impact of the Swede's arrival can last beyond the Asian Cup finals.
The Azkals will play in the continental championship for the first time. But it was the appointment of the former England manager on a short-term contract in October that grabbed global attention for Philippine football.

Since his appointment in August, Paulo Bento has had little time to get to grips with the job but with the South Koreans unbeaten in his six matches in charge, optimism is building ahead of their opener against the Philippines in Dubai on January 7.
South Korea's task in the group stage has been made more difficult due to the absence of captain Son Heung-min, who will sit out the first two games under an agreement with his club side Tottenham Hotspur.
However, the South Koreans should still have enough firepower to see them through to the knockout stage, with Gamba Osaka striker Hwang Ui-jo enjoying a rich vein of scoring form and Ki Sung-yueng impressing at the heart of the Newcastle United midfield.
