Tottenham faces potential defensive concerns ahead of its Monaco fixture after captain Cristian Romero and defender Destiny Udogie missed training, but Sky Sports reports neither injury appears serious. Romero withdrew from the session before the Aston Villa match because of an adductor problem, and Kevin Danso replaced him in the starting lineup. Udogie sustained a minor knee issue that required him to sit out the preparatory work. The remaining players who featured against Aston Villa trained without complications on Tuesday, and this development provides encouragement for manager Thomas Frank as his squad navigates a congested fixture list.
