Karim El Ahmadi impressed by new Villa pal Sylla
El Ahmadi was impressed with Sylla's powerful presence on the training field and his brief cameo debut at Goodison Park.
He told Villa's website: "Yacouba is the sort of player we need in this situation. He's a strong guy and a good player. He's more than welcome.
"It will be good for the team to have that competition in central midfield. I think both new signings are players we need at this moment in time.
"I think Yacouba is a good player. I faced him directly in some tackles in training and you can see he is a good player.
"He's a strong guy too and that is something we need."
