Pundit Paul Merson has told Sky Sports that he thinks Sunderland did well bringing in defenders in January - but has concerns about their attacking options.
The Black Cats, who lost 1-0 at home to Manchester City on Tuesday night, are mired in a relegation battle, and find themselves four points adrift of safety.
Manager Sam Allardyce was busy in the January transfer window, bringing in a host of new faces to strengthen his relegation-threatened side.
Goalkeeper Steve Harper, formerly of North East rivals Newcastle, arrived to offer some experienced cover for Vito Mannone and Jordan Bickford, whilst German utility man Jan Kirchhoff - who can play in holding midfield or at centre back - joined from Bayern Munich.
Centre back Lamine Kone also signed from Lorient after a protracted transfer saga, whilst Tunisian international playmaker Wahbi Khazri followed him from France to Wearside, signing from Bordeaux after starring in Ligue 1.
Sunderland also managed to secure a deal for Trabzonspor striker Dame N'Doye, with the former Hull City man arriving on loan until the end of the season, with Allardyce hoping that he can score the goals to save his side this term.
Now, pundit Paul Merson has had his say on Sunderland's dealings, suggesting that even though he isn't familiar with all of their signings, he trusts Allardyce's homework in the transfer market.
Merson also told Sky Sports that he thinks Sunderland didn't do enough to give Jermain Defoe support in attack, and worried that the Black Cats won't have the goals to survive.
"This is a hard one but you can't doubt Sam Allardyce because he does his homework," said Merson. "He's got to bring defenders in who are going to keep them in touch for the next five games because their next five fixtures are a joke. Then after that, when they've got to win games, are they going to have enough to win them because they haven't bought strikers?"
"It could go horribly wrong. If they do get draws and a few points in the hard games then they've got to go and win games and I don't think he's got the firepower to win them, apart from Jermain Defoe," he added.
