Gaffer explains that former AC Milan defender comes "highly recommended".Darren Ferguson hailed the arrival of Brazilian loanee Felipe Mattioni until January.
The Everton loanee could make his debut on Saturday in the FA Cup first round, just months after playing in La Liga.
“His last game was against Real Madrid for Espanyol and his first game for us might be Stalybridge,” said the Scot.
“It’s a bit of a contrast!
“He’s a good player. His CV is quite outstanding really. He’s a good technician; he’s a full back who can play wing back.
“He plays similarly to what we want to do. He’s a decent defender and Roberto (Martinez) has highly recommended him so you have to go with that because he’s a good, experienced manager.”
Mattioni joins his new Toffees teammate Conor Grant at Keepmoat Stadium and the latter could not have wished to make a better impact on his debut against Colchester United; scoring a wonderful curled effort from 25 yards.
“Both of them coming together is always a good thing,” said Ferguson.
“Conor is a good player; we know he can get a goal. We encouraged the players to have a shot and it’s just a beautiful goal. He will get better; he's not used to the high energy and tempo.
“We watched Conor play at left back but we thought that he could fill in in midfield and we had to take him before anyone else did!
“The result won’t change the fact that I’m still after a defender but they (Grant and Mattioni) can improve us.”
Will Mattioni make his debut on Saturday?
