Adrian Boothroyd believes there is plenty more to come from Steven Kabba after the striker signed for Watford following a £500,000 transfer from fellow Premiership strugglers Sheffield United.
The 25-year-old Londoner has agreed a two-and-a-half-year deal at Vicarage Road to bring to an end a spell of more than four years in south Yorkshire following a £250,000 move from Crystal Palace in November 2002.
Kabba endured a number of injuries during his time at Bramall Lane but his nine league goals last season and partnership with Neil Shipperley was instrumental in the Blades' fine start which culminated in promotion to the top flight.
The forward scored a total of 23 goals in 53 league and cup starts for the Blades but he has not started a Premiership game this season and made his final appearance as a substitute in the 1-0 defeat at West Ham in November.
Blades boss Neil Warnock has allowed Kabba to move to their relegation rivals and Boothroyd revealed the forward was just the type of player he had been seeking as the Hornets look to pull off an improbable escape from the drop.
He said: 'Steve fits the bill. He threatened to really kick-start his career at the beginning of last season when he was on a good goalscoring run.
'He is quick, has an eye for goal and has got loads of development left in him at 25 years old. A great addition to our squad.'
Kabba joins Will Hoskins and Moses Ashikodi as the new arrivals to a forward line which has managed just 14 goals this season with Ashley Young, who switched to Aston Villa earlier this week for £9.65million, the leading scorer with just three goals.
They have also been severely hampered by the absence of Marlon King who is out for the season after being injured against Arsenal in October.
Kabba will not be making his debut in the Hornets' FA Cup clash with West Ham at Upton Park on Saturday.
Defender Malky Mackay, though, insists the team have taken confidence from their 2-1 win over Blackburn in midweek and still believe they can beat relegation.
Mackay said: 'We still have plenty of games to go, and we are closer now to the fourth-bottom side after the win over Blackburn.
'There are lots of points to play for and (we have) no defeatist attitude about us at all.
'The manager here is always positive with us. It is not a mask, that is the way it is.
'When the FA Cup comes around it is great, and every player would love to get to a cup final.
'Coming off the back of a win certainly helps us for this next game.'
The former Scotland international spent a year at Upton Park before moving to Vicarage Road in the summer of 2005 and the 34-year-old is looking forward to returning for the fourth-round clash.
He said: 'I'm delighted to be going back there. There has been a big change at the club this season, but going back as a former club, it'll be great.'
However, Mackay admits the Hertfordshire club have not fired in front of goal this season and will no doubt be cheered by Kabba's arrival.
'All the matches we have played have been fairly even, it's just the goals which have been the difference between getting points.
'You have to score goals from all over the pitch, and work on set pieces.
'We do that every week to get goals from wherever we can, and if the strikers aren't producing at the moment then it has to come from other places.
'We're happy whoever scores - at the moment we're just happy if we get a goal.'
Mackay also reserved praise for striker Darius Henderson who has failed to score this season.
'I'm sure Darius has found it hard,' he added.
'Anyone's confidence must dip a little but he is strong and I think he will have confidence now as we are telling him how well he is doing for us.'
