Alex Ferguson is sweating on the fitness of Louis Saha and Cristiano Ronaldo ahead of Manchester United's Premiership clash with Everton at Old Trafford.
Saha was taken off before the end of Sunday's draw with Chelsea after suffering a slight knock, while Ronaldo failed to return after going down under a hefty challenge from Ashley Cole.
Although Ole Gunnar Solskjaer and Park Ji-Sung are due to return to training this week after overcoming hamstring and ankle injuries respectively, neither will come into consideration for Everton's visit and, with Alan Smith now on a personal fitness programme and Giuseppe Rossi kicking his heels at Newcastle, Ferguson could be left with just Wayne Rooney as an orthodox forward.
Should neither Saha nor Ronaldo make it, Rooney could be joined in attack by Ryan Giggs, with Darren Fletcher and John O'Shea drafted in to fill the vacant midfield slots.
The problem just highlights the lack of depth in Ferguson's squad compared to Chelsea, although the imminent return of Solskjaer and Park is welcome news at such a congested stage of the season.
Solskjaer has already confirmed his well-being with six goals this term, while Park's industry could certainly come in handy as Ferguson looks to ease the burden on Giggs and fellow veteran Paul Scholes.
