Whether Aston Villa or Tottenham covers the specified handicaps (−1.5 and −2.5) and whether the match exceeds each total-goals threshold (1.5, 2.5, 3.5, 4.5).
Both-teams-to-score (BTTS) settles independently and alters the payoff profile of combined spread/total wagers.
Aston Villa and Tottenham Hotspur are the principal actors, with each club’s attackers and goalkeepers most likely to swing spreads and totals.
Team managers, substitutes, and the match official matter too through selection choices, tactical changes, and disciplinary decisions that affect scoring margins.
Recent form, shot conversion rates, and defensive solidity shift odds for wide margins and different total-goal bands.
Injuries, suspensions, tactical setup (high press versus low block), set-piece threat, and weather or pitch state are the main causal levers.
Starting lineups and late injury or suspension updates, usually published about an hour before kickoff, are immediate pre-match signals.
Also monitor referee appointment, expected-goals models, announcements about rotations or fatigue, and any early red cards or penalties that can flip spreads and totals.
