Chris Coleman has admitted that Sunderland's current search for new signings is proving to be a "dogfight".

The 47-year-old made his first signing as Black Cats boss earlier this week by bringing Jake Clarke-Salter in from Chelsea on a loan deal.

Coleman revealed in December that Sunderland were expected to be operating on a tight budget but the Welshman believes that more signings will be made before the transfer window shuts.

"We want to bring in new faces but it has to be the right personality coming into the dressing room to help what we've already got," Coleman told the Sunderland Echo.

"That isn't easy because of course other clubs in a similar situation want to take loan players. It is a dogfight but getting Jake is a good start for us and there's still two, three of four more we'd like to do before the end of the window.

"Immediately you feel here what type of club it is, the difficulty it is in. I think it has had a lot of turnover in terms of player ins and outs, a lot of money has been spent and it hasn't quite worked out.

"We need to be realistic in where we are, and the reality is at this moment in time we can't spend millions on players, but even if we could the principle would be the same, getting the right personalities."

Sunderland currently sit bottom of the Championship table.
