Leicester City manager Brendan Rodgers says he is "not a magician" as he tries to keep his side competing with their rivals.
Leicester's only outlay last summer was on defender Wout Faes and they are yet to sign any players in January.
"It's becoming a real challenge," said Rodgers.
The Foxes are 13th in the Premier League after three consecutive defeats but they go into the game against Newcastle on the back of beating Gillingham 1-0 in the FA Cup.
"I think I'm a decent coach, but I'm not a magician," added Rodgers, who took charge in 2019.
