MLS is in my opinion, about equivalent to the Championship from the research I have done.
According to WhoScored.com, he has an average rating of 7.25 whilst playing in the MLS, which I consider to be equivalent to a Premier League player getting a rating of approx 6.8, which for this season would put him in the Top 80 Premier League players, on the basis of the rating system used by WhoScored.
I can't give any personal opinion because I have no idea who he is, whether he is good or not, or would fit our system (whatever that is

),so can only compare him against the list of data I have to see where he fits within that remit.
