I found on internet a template for thesis, but I don’t like the chapter titles. I really want to make them look like as in the picture below.

Do you know how to make it?

I’ve tried with this:

% Redefine the chapter command to make the number large and red, and the title on a new line
makeatletter
def@makechapterhead#1{%
    vspace*{50p@}%
    {parindent z@ raggedright normalfont
        ifnum c@secnumdepth >m@ne
        Hugebfseriestextcolor{red}{thechapter}parnobreak  % Extra large, bold, and red chapter number
        vskip 2p@
        fi
        interlinepenalty@M
        Huge bfseries #1parnobreak
        vskip 40p@
}}
makeatother

But it is not the style I am looking for and I can’t make the title number bigger.
