The West Ham striker has praised his team-mate's ability on the ball.
Both Hammers stars scored during their side's 3-0 win over Hull City on Sunday, with the latter producing a silky, chipped finish to round off the three-goal victory.
And Carroll has hailed the on-loan Frenchman for his impressive ability with the ball at his feet.
"They were great goals. Morgan is unbelievable with his feet and he was so cool and composed and dinked it over the 'keeper, then obviously it was a great ball by Alex Song to put Stewie (Stewart Downing) in," the West Ham striker said of his team-mate.
Interestingly, the east London side's co-chairman David Gold also praised the French midfielder recently, although he stated his opinion that the 29-year-old is much better for the Hammers coming off the bench.

As Opta stats show, Amalfitano is Sam Allardyce's fourth-most used substitute, which suggests the West Ham boss turns to him to change a game - but also that he is not as frequent a starter as he could be.
With his obvious technique on the ball, however, the midfield man has proven himself as a transformative presence from the bench, so to speak.
And Carroll, at the very least, certainly rates him highly.
