Manchester United currently have "more problems than solutions", says head coach Ruben Amorim.
The Red Devils suffered a 1-0 defeat at Tottenham on Sunday, taking their tally to 12 Premier League defeats in 25 matches so far this season.
They have won only four of the 14 league games since Amorim took charge in November and travel to Everton on Saturday (kick-off 12:30 GMT), with the Toffees rejuvenated since David Moyes - who succeeded Sir Alex Ferguson as Manchester United manager - took charge.
Much has been made about United's issues at both ends of the pitch - keeping only seven clean sheets at the back and netting just 28 goals up front.
