Stats Zone quarter-final preview: deep forwards, midfield runners and the narrowest team

Zambia v Sudan (Sat 4 Feb, 4pm)
Sudan are one of the narrower sides in the competition, as shown by the diagrams from their 2-1 win over Burkina Faso in their final group game.

The narrowness can be observed in two distinct ways. First, with the exception of one corner, all their chances were created by a pass played from a central position, including goalkeeper Akram El Hadi SalimâÂÂs blatant hoof down the pitch for the second goal, finished nicely by Mudather El Tahir.

Second, they barely ever cross the ball. From the 12 crosses they attempted against Burkina Faso, six were from corners. In other words, they only attempt a cross from open play once every 15 minutes, so Zambia should primarily be concerned with keeping it tight down the middle of the pitch.

Ivory Coast v Equatorial Guinea (Sat 4 Feb, 7pm)
Equatorial GuineaâÂÂs Juvenal â full name Juvenal Edjogo-Owono Montalbán â is really a Spanish player. Born in the Catalonian city of Sabadell, he joined his hometown club at the age of 29 in 2008.

His style of play is typical for a player from that region. HeâÂÂs an excellent passer, possibly a natural No.10, but spends much of the game coming deep to get the ball before spraying it across the pitch for team-mates.

HeâÂÂs also stormed forward to have plenty of shots in his three matches so far, and is probably the biggest threat to the physical Ivorian midfield three of Cheick Tiote, Yaya Toure and Didier Zokora.

Gabon v Mali (Sun 5 Feb, 4pm)
Modibo Maiga plays an interesting role for Mali, who take on Gabon this weekend. The forward, who was heavily linked with Newcastle last summer but has remained at Sochaux, plays as a deep-lying forward but isnâÂÂt really based around creativity in the traditional sense â he plays more of a hold-up role, laying the ball off to midfield runners.

The diagrams below show that a very high proportion of his passes are played backwards rather than forwards, although they can be highly effective â he created four chances with pull-backs in the 2-1 win over Botswana.

Ghana v Tunisia (Sun 5 Feb, 7pm)
As at the World Cup two years ago, Ghana seem set up to play on the counter-attack, and like to work the right-hand side of the pitch more than the left. On that side they have Andre Ayew, a true forward rather than the more functional player on the other wing (either box-to-box midfielder Sulley Muntari or full-back Samuel Inkoom are used on the left).

Furthermore, their right-sided central midfielder, Emmanel Agyemang-Badu, breaks forward much more than the left-sided holder, Anthony Annan, does. BaduâÂÂs Udinese teammate Kwadowah Asamoah, the central attacking midfielder, also likes to move across to the right.

In their previous game against Guinea, they only managed to create three chances in the game, but all came from the right. This means TunisiaâÂÂs left-back will be in for a big test. Ammar Jemal started TunisiaâÂÂs first game of the tournament there, but Khalil Chemmam was used in the win over Gabon. His dashboard reveals a fine performance, and heâÂÂll need to replicate that on Sunday.
