I needed a left back for a long time in my team and tried all sorts. Mendy was bad at defending and Robertson was too slow. Rose however was the perfect balance with great skills going forward and in defence and can keep you in games. For 5k I would highly recommend him as you will not find anyone better in the league.
Strength as he out-muscles opponents all the time
Occasionally gets a yellow card but its not a concern as he has never got sent off for me.
