Zambia hit the ground running on Tuesday after arriving back from Swaziland on Monday night, 24 hours after their emphatic 4-0 away win in a 2018 CHAN qualifier.
Chipolopolo got down to business on Tuesday afternoon at National Heroes Stadium in Lusaka where they will host Swaziland on July 22.
But Zambia coach Wedson Nyirenda has refused to treat the home leg training camp as holiday despite the resounding result in Swaziland.
“It is not training with a jovial mood.It will be intense,” Nyirenda warned.
“They have to know that we are not here to joke. We have had such cases in the past where we have had an advantage of one or two goals and we start relaxing and we have negative result.”
Zambia must beat or draw against Swaziland this Saturday to advance to the final qualifying stage in August for the tournament Kenya will host this January.
South Africa or Botswana await in August in the battle in final leg for that ticket to Nairobi.

The two sides meet in South Africa on July 22 at Moruleng Stadium.
Meanwhile, Nyirenda has summoned Nkana defender Moses Nyondo for the final leg match against Swaziland.
