Swansea City manager Carvalhal has explained the reason behind the substitution of Andre Ayew during his side's 4-1 win over West Ham United on Saturday.
The 28-year-old rejoined the Swansea during the January transfer window deadline day from West Ham United after failing to hit stride in London.
The Ghana forward was in his element for the Welsh-based side during their 4-1 thumping of his former club as he was involved in three of the goals they scored, including a late a penalty which his younger brother Jordan Ayew coolly buried.
However, despite Ayew's superb performance, he was replaced with Nathan Dyer in the 78th minute to the chagrin of their teeming supporters at the Liberty Stadium.
“When they [Ayew and King] came to us, they had not played a lot of football so it was difficult to put them straight into the team,” Carvalhal shed light on his decision after the game.
“The way we play and what we want to do is something their bodies must get used to."
“Maybe now, after three or four weeks, we felt they were completely ready and they showed that with the way they played."
“But we understand they have not played for a long time and that’s why we brought them off, to protect them from any injuries.”
Despite the Ayew brothers have heavily featured in the post-match talks, the Portuguese trainer refused to single out any one man for praise.
“When you win 4-1, I don’t think it is about one player,” said the Swans boss.
“I think it’s fair on a day like this to talk about the collective. We have two brothers in our team, but it looked like we played with 11 brothers today."
“There were 11 players on the pitch and another three who came on. There were others in the squad and even those who are injured – Wilfried Bony, Leroy Fer and Angel Rangel - who I saw today. "
“We have a good commitment here – a good family. The players are like brothers and we felt all together today.”
Ayew has made three league appearances in all since his switch to the Welsh based side in January.
