Bryan Robson has signed the likes of Brazilian midfielder Juninho and other expensive internationals-during his management-career.
But if Robson succeeds in keeping West Bromwich Albion in the Premiership against the odds this season, then the Baggies boss says he will probably regard Kevin Campbell as his best ever signing.
Campbell has been a revelation at The Hawthorns since Robson astutely signed the 35-year-old striker on a free transfer during the January transfer window.
The former Everton forward, who now captains Albion, has responded with three goals in eight league games and Robson says Campbell could turn out to be one of his most inspirational acquisitions.
"If we stay up, Kevin will be definitely be right up there with my best signings," said Robson yesterday.
"Nigel Pearson and Andy Townsend were two captains I had at Middlesbrough who were terrific signings for me - and Juninho was superb because of his flair.
"But if we were to stay up and Kevin scores a few more goals this season then he is going to be classed right up there with those type of lads."
Robson has assured Campbell he will start against his old club in Sunday's home league game and the manager believes Everton's loss has been Albion's gain.
He added: "Campbell will definitely play and he'll really be looking forward to playing against Everton.
"He has done a terrific job since he came to the club and a lot of his characteristics have rubbed off on the other lads. He's a really good professional and a bubbly person - he is a great character to have around the place.
"That rubs off on other people and they are starting to enjoy training. The lads have a bit of banter among themselves and that's an important factor at a club.
"Kevin has also always scored one in three games and that's a terrific record to have at this level."
Robson's insistence on playing Campbell against his old club this weekend makes it unclear if Rob Earnshaw will start - despite his impressive hat-trick at Charlton in Albion's previous game after coming off the bench.
Robson could adopt a 4-3-3 formation with Earnshaw joining Geoff Horsfield and Campbell upfront, or he could drop Horsfield in favour of the Welsh international.
But with Horsfield - also on the scoresheet at The Valley - forming a useful partnership with Campbell, the likelihood is Earnshaw will again be a substitute.
Robson, who also has Kanu at his disposal, added: "The four strikers are doing really well because they are making it a very difficult decision whether I go 4-3-3 or whether I go with two and which ones do I pick.
"They know they are making life for me as a manager very difficult but it is my job to choose.
"When I look at Rob Earnshaw's performances he always starts off games really brightly and puts a lot of energy into the game.
"You send Rob on as substitute and he is always going to be a threat because as the opposition are tiring, he is full of energy and is very difficult to stay with because his movement is very good.
"But I don't want Rob to get it in his head that I am thinking he is going to be a sub all the time.
"There will be starting positions for him, I have just got to assess the teams we are playing against and whether we can get a grip in the game. Sometimes we have to stay in the match and use Rob to get us a goal late on."
Robson also confirmed that Albion's young midfield duo of Richard Chaplow and Kieran Richardson have been shortlisted for England's Under-20 squad for the prestigious Toulon Tournament in France this June.
He said: "Some managers might say the young lads need rest this summer but I think it would be a fantastic experience for both of them and I hope they both get into the full squad." n Championship side Watford yesterday announced former Albion coach Adrian Boothroyd, aged 34, as their new manager.
Boothroyd, who possesses a Uefa 'A' coaching certificate, takes over from Ray Lewington after positions with Peterborough United, Norwich City, Albion and latterly Leeds United.
