Least of our problems today.
A 21 year old in his first season of senior football should not be the difference between you beating a newly promoted side. He did his job fine, he lost a couple of balls when isolated but other than that did everything asked of him, including an excellent pull back for Ramsey.
If you expect him to be a Marcelo you will be disappointed. He should be viewed as an inexperienced young player asked to fill in during an injury crisis. He has been tidy and overall has done more than I would have expected from him. I'm happy to have him as a low cost squad option.
