Roma coach Luciano Spalletti admits he has concerns about this week's Champions League clash with Manchester United after last night's 4-1 thrashing at home by Inter Milan.
Inter coach Roberto Mancini's tactical choices also caused problems for Spalletti, as he surprisingly fielded a 3-4-2-1 system with Zlatan Ibrahimovic as lone striker.
"If they had two forwards, there would have been less need to scale back, but this way we always had to move a central midfielder out of position. Inter had the numerical advantage and an extra figure in midfield too."
