Swansea manager Carlos Carvalhal has called the January transfer window a 'nightmare', as the new boss struggles to get deals over the line.
Speaking to Sky Sports, the Portuguese boss admits he has grown frustrated with negotiation problems, which make him feel 'nervous'.
''Negotiations put me a little nervous I must tell," the former Sheffield Wednesday boss said. "Sometimes you think everything is sorted, then there is another problem and another problem.''
Despite sitting bottom of the Premier League table, Swansea have been linked with numerous high profile signings this window, including moves for Athletico Madrid striker Kevin Gameiro and AC Milan forward Andre Silva.
