I'm almost certain Holgate is coming in to replace Tosin at right back. He's a more suitable height, more agile, quicker, better on the ball and slightly more attacking. Still not a natural RB, but Tosin is really struggling at the minute, keeps getting caught out by wingers and can't get back in time to cover.
Gibbs - Hegazi - Dawson - Holgate is the best back 4 in the league on paper.
