The Argentine forward has become the odd man out in United's strike force this season with Wayne Rooney and $48million signing Dimitar Berbatov the first-choice forwards for the English Premier League champions.
Not following orders
Tevez was handed only his fourth league start of the season in the 2-0 win over West Ham United on Wednesday and in his attempt to impress failed to follow team orders.
"On Wednesday, I wanted to see how the combination of Berbatov and Tevez was together," Ferguson said on Friday.
"But Carlos was so wound up to do well himself that they became two different parts.
"Carlos was so keen to do well he used up too much energy, but it is not a bad thing to try too hard.
"I think they will be far better tomorrow, if I pick them."
