ANKARA (AA) - English Premier League side Manchester United don't have a transfer budget for January window, the British media reported on Tuesday.

To comply with the Premier League's profitability and sustainability rules, the Red Devils will be unable to sign new blood for the squad, unless selling any players, according to sports news website Manchester Evening News.

After spending more than £200 million ($251 million) in the summer window, the United management had hinted that new manager Ruben Amorim was planning to use a "lower budget" in November.

After losing to Newcastle United 2-0 at Old Trafford on Monday, struggling Manchester United lost four games in a row in the league for the first time since 1961.

Portuguese manager Amorim, who took over the spot from Dutch Erik Ten Hag in November, has so far failed to impress United fans.
