Ruud van Nistelrooy is reportedly unhappy with the lack of transfer activity at Leicester.
Seven weeks after his hyped appointment, the Dutchman finds himself in a difficult situation after failing to improve the Foxes' form.
With just one win in their last nine games in all competitions, which was against Championship side QPR in the FA Cup, things are looking bleak.
Despite their difficulties, Leicester have only made one signing in the January transfer market: right-back Woyo Coulibaly.
Now, according to the sunVan Nistelrooy is increasingly frustrated by the lack of income at the club as they look to fight for Premier League survival.
When asked about Coulibaly's signing, Van Nistelrooy replied: “It's a good start”, with the clear inference that it shouldn't be the end of the spending.

Right-back Coulibaly signed from Parma and will make his Tottenham debut next weekend.
Three of the Foxes' fourth quarter were in their relegation squad from two seasons ago and 38-year-old Jamie Vardy remains their best hope of scoring as substitute Patson Daka has scored once in his last 22 games.
Van Nistelrooy felt the wrath of angry Leicester fans as they suffered a seventh successive league defeat at a toxic King Power Stadium.
Leicester are now on a seven-game losing streak after their 2-0 home defeat to Fulham.
Fed up fans also called out director of football Jon Rudkin and chanted “Sack the Board,” which is never a good sign for coaches in case owners are looking for a scapegoat.
Van Nistelrooy did not try to hide the reality afterwards: “We were not good enough in all aspects of the game,” the Dutchman admitted.
“I have to accept the reaction, but just because the public boos a substitution doesn't mean I have to explain the reasons.
'The players have to face the situation. We are professionals.
