Switzerland head coach Yakin has some serious selection worries ahead of Tuesday's World Cup contest.
“Obviously, if they have to quit the training session earlier, everybody is very annoyed because this is going to be a very big loss,” Yakin said.
“If they might not play tomorrow, it could be a huge issue for us.”
Freiburg forward Manzambi has emerged as one of Switzerland's standout performers at the World Cup. The 20-year-old has scored three goals while providing two assists, and his absence would be a bitter blow for Yayin's side.
Breel Embolo and Dan Ndoye both scored in the win against Algeria, and will keep their places in the first XI.
Colombia Squad
Goalkeepers: David Ospina, Camilo Vargas, Alvaro Montero
Defenders: Daniel Munoz, Jhon Lucumi, Santiago Arias, Yerry Mina, Johan Mojica, Willer Ditta, Deiver Machado, Davinson Sanchez
Midfielders: Kevin Castano, Richard Rios, Jorge Carrascal, James Rodriguez, Jhon Arias, Gustavo Puerta, Juan Portilla, Jefferson Lerma, Juan Fernando Quintero, Jaminton Campaz
Forwards: Luis Diaz, Jhon Cordoba, Cucho Hernandez, Luis Suarez, Andres Gomez
Nestor Lorenzo has no major fresh injury concerns reported ahead of Tuesday's knockout clash.
Jhon Arias should keep his place after scoring the winner against Ghana, while Luis Diaz and James Rodriguez are expected to start.
Luis Suarez is likely to return to the first XI after replacing Jhon Cordoba in the first half of the win against Ghana.
“After creating several chances and not converting, I liked how we defended,” Lorenzo told reporters.
“I value the fact that we did not suffer much, apart from the opponent's clear chances,” Lorenzo added.
