Spurs are down a defender the next 3-4 weeks (or more) with Vertongen's injury this week. No clue if they'd sign him, but they need depth on the back line (and Klinsman is a former Spur star).
I read that after the USMNT camp is over that he will spend the rest of the season with Chelsea before deciding on where to loan him out. Chelsea only has like 28 players on loan lol.
Miazga had a huge breakthrough year last season. He went from being a backup to a full timer right from the start of the season. I saw him in the season opener when they played KC and he basically already looked like a Top 10 center back in the league.
This is how MLS needs to progress. Get the big clubs in the big leagues to buy young players that are Top 10ish in the league and make money. Over time the league will become less likely to want to sign retreads like Ashley Cole and Van Damme.
