Fulham boss Martin Jol admits he only had to look at his bench against Newcastle to know he needs reinforcements in his squad.
An unfit Andrew Johnson was the only attacking option for Jol, who used just one sub in trying to overhaul a two-goal deficit during a 2-1 defeat at Newcastle.
Johnson was able to liven up Fulham's goal threat, but it was not enough to rescue the visitors, and Jol now concedes investment is essential before Wednesday's 11pm transfer deadline.
"Johnson was the only attacking player on the bench in the second-half and he wasn't 100 per cent fit, then you know you need a couple of players to add competition," he told Sky Sports News.
"You don't have to be great at mathematics to realise that if nine players have left the club and four have come in, you need some players."
Still without a Premier League win, Fulham have been linked with moves for West Brom forward Jerome Thomas and Birmingham's Cameron Jerome, but Jol has so far been left frustrated in the market.
And the Dutchman's need for a natural finisher was evident at St James' Park on Sunday as his side wasted a series of chances, with Newcastle goalkeeper Tim Krul in inspired form.
Jol added: "All credit to the young goalkeeper because he's from my home town. I like him, he's a great talent.
"I thought we were the better team, particularly in the first part of the first-half, but you have to capitalise on that sort of possession.
"You have to score. I think we created eight or nine chances away from home. Then they came out and they scored a goal because we couldn't concentrate.
"We were the better in spells and if we'd have capitalised on that we would have had a better result."
"Hopefully we'll return more fresh [after the international break] but I think we should have had a result here."
