There had been fears that Musa may not be at the peak of his powers when the Super Eagles take on France in Brasilia on Monday.
Keshi, however, is not bothered as he believes Musa has been a professional footballer for a long time and this was not the first time he would have to play during the Ramadan period.
“Musa is a professional; he knows what he has to do. I don’t think the fasting will affect his performance against France and am sure he will put in the same level of performance irrespective of the situation”, Keshi told reporters.
“He’s (Musa) going to observe Ramadan. It’s a normal thing to do. He’s used to it.
“He plays for his club when he’s fasting and does what’s expected of him. He’s going to do the same thing on Monday if he’s selected”, Keshi concluded.
Ramadan is the ninth month of the Islamic calendar and Muslims worldwide observe it as a period of fasting.
While fasting from dawn until sunset, Muslims refrain from consuming food, drinking liquids, smoking, and engaging in sexual relations.
With the temperatures in Brasilia on Monday expected to reach 28 degrees and humidity of almost 72% predicted, the winger is widely expected to struggle with the conditions.
The CSKA Moscow player, who netted a brace against the La Albiceleste has commenced religious observance of the month of Ramadan.
