A look at the teams, key players and coaches in Group D at the African Cup of Nations:
GHANA
When will the pain end for Ghana? No team has had to deal with more near-misses in the recent history of the African Cup. Always among the favorites, the four-time champions haven't tasted any success in 35 years and have lost three finals and four semifinals since its last title in 1982. Ghana has the players, it just needs to find the mental strength to break the losing run.
KEY PLAYERS: Asamoah Gyan, Jordan Ayew and Christian Atsu
Ghana's attacking trio must re-produce the form that took the team to the 2015 final - and crucially deliver in the final this time - if Ghana is going to finally get its hands back on the African Cup.
COACH: Avram Grant
Grant led Ghana to the 2015 final barely a month after being appointed, but two years down the line his job may be under threat if Ghana doesn't win in Gabon. Ghana is in danger of missing out on the 2018 World Cup, meaning the African Cup could be the saving grace for the former Chelsea manager. He faces a stern test to guide his team through a group that also contains Egypt and Mali.
BEST RESULT: Winner, 1963, 1965, 1978 and 1982.
MALI
The team that had the cruelest experience in 2015 when it was denied a place in the quarterfinals through the drawing of lots. Mali and Guinea finished with identical records in their group, leaving a Guinean official to pick the winning ball out of a bag and eliminate Mali from the tournament. That ended a run of two successive third-place finishes for Mali. Mali faces tough group opposition in Ghana and Egypt in 2017 and doesn't have talismanic midfielder Seydou Keita anymore.
KEY PLAYER: Adama Traore
Without the retired Keita, the focus will be on Monaco's Traore to run Mali from midfield, with help from Werder Bremen's Sambou Yatabare.
COACH: Alain Giresse
Giresse is back for a second spell in charge of Mali, a team he took to the semifinals and ultimately third place in Gabon and Equatorial Guinea in 2012. Giresse also previously coached Gabon, so he's likely to feel right at home at this tournament.
BEST RESULT: Runner-up, 1972.
EGYPT
The most successful team in Africa is back. Egypt has won seven titles, and claimed three straight from 2006-10, but after beating Ghana in the 2010 final, it failed to qualify for the next three tournaments. Politics contributed to that, with the slump coinciding with revolution and upheaval at home. Egypt has had a strong revival, though, and its squad for Gabon has a good balance of home-based and Europe-based players. Goalkeeper and captain Essam el-Hadary, who is 43, won with Egypt in 1998, 2006, 2008 and 2010.
KEY PLAYER: Mohamed Salah
The speedy Roma forward leads Egypt's attacking threat with his ability to score goals and create opportunities for others. This is the 24-year-old Salah's first opportunity to showcase his talent at an international tournament.
COACH: Hector Cuper
Egypt found the right man in Hector Cuper after Bob Bradley and Shawky Gharieb couldn't get Egypt back into the African Cup. The Argentine is a former Inter Milan and Valencia coach and has created a tactically impressive Egypt team.
BEST RESULT: Winner, 1957, 1959, 1986, 1998, 2006, 2008 and 2010.
UGANDA
Uganda had to wait much longer than Egypt to return to the African Cup: This is its first trip to the championship in 39 years. That means that apart from debutant Guinea-Bissau, Uganda is the most inexperienced team in Gabon. That won't matter for the Ugandans, who have faced all sorts of challenges on their way to Gabon, most recently a severe lack of money to fund their trip. Politicians back home came to their aid, with every Ugandan lawmaker agreeing to take a pay cut of $138 this month so that the money can be sent to the team.
KEY PLAYER: Geofrey Massa
Goalkeeper Denis Onyango is often the hero for Uganda but the Ugandans will need more than that if they are to make an impact on their long-awaited return, meaning captain and striker Massa will be arguably more important.
COACH: Milutin Sredojevic
Serbian Sredojevic managed to negotiate Uganda through qualifying and to the African Cup despite a severe lack of financial resources. He's also not afraid to talk his team up, taunting Ghana coach Avram Grant after Uganda's 0-0 draw in Ghana in World Cup qualifying last year, and saying his team has got Ghana's number. Uganda faces Ghana first in Gabon.
BEST RESULT: Runner-up, 1978.
