Swansea City boss Garry Monk says he hopes to add to his squad before the transfer window closes on Monday.
The Swans are second in the Premier League, behind Chelsea on goal difference, after beating West Brom 3-0 on Saturday.
Monk says the Welsh club are under strength and need to buy more players.
"We can't afford to lose anyone," he said. "We are not at full strength in the squad. We need a couple of extra bodies in case something happens."
Victory against the Baggies gave Swansea a third successive win for the first time as a Premier League club.
Including their League Cup victory against Rotherham, it is their best start to a season for 91 years.
Their next match is a top-of-the-table encounter at Stamford Bridge against Chelsea on Saturday, 13 September and Monk is hopefully of having new faces in his ranks before then.
"I've identified the targets and given them to the board and chairman and hopefully they can come through," he said.

Monk has been busy in his first transfer window at the helm.
Wales full-back Ben Davies and goalkeeper Michel Vorm have left for Tottenham, with midfielders Gylfi Sigurdsson and Tom Carroll (loan) heading to Wales.
Michu has been loaned to Napoli, with Argentina defender Federico Fernandez leaving the Italian side for the Liberty Stadium.
Other Spaniards to leave the Welsh club include Chico Flores (Lekhwiya SC), Alejandro Pozuelo (Rayo Vallecano) and Pablo Hernandez (Al Arabi).
South Korean midfielder Ki Sung-Yueng has returned from his loan spell at Sunderland and signed a new contract.
Monk has also added goalkeeper Lukasz Fabianski, striker Bafetimbi Gomis and forwards Marvin Emnes and Jefferson Montero to his squad.
"I talked about having 22 senior professionals at the club and then the younger lads complement that, obviously developing them to come through," said Monk.
"We are not there and need that couple of extra bodies."
