Chris Sutton will need to be vigilant in Birmingham City's dressing-room as their chief prankster possesses a long memory.
When Birmingham's latest signing was terrorising Premiership defences with Alan Shearer in 1995, David Dunn was a fresh-faced apprentice at Ewood Park.
Dunn would look on in awe at the SAS partnership that ensured Blackburn became the first team to break Manchester United's monopoly on the Premiership title.
Sutton moved to pastures new at Chelsea while Dunn graduated to first-team regular and England international at Rovers.
However, they were reunited last week when Sutton became Steve Bruce's first signing in the transfer window to bolster his squad for the relegation battle ahead.
Dunn is a confirmed fan of Sutton's talents and is salivating at the prospect of linking up with the Scottish Player of the Year in 2004.
However, Sutton can expect some good-natured ribbing from Dunn and his Rovers team-mate at the time, Martin Taylor.
The towering centre-half was Sutton's designated boot-boy and he and Dunn were on the receiving end of Sutton's razor-sharp tongue when the dressing-room humour sparked into life.
Dunn said: "Chris is a very good signing and his record speaks for itself.
"Martin Taylor used to clean his boots, so we were always talking to him and Chris used to cane us as we were just first-year YTS players!
"He was in his heyday at Blackburn and we took a bit of stick from him, but it was all very good-natured.
"Nevertheless, it is a bit weird seeing him here now and I've got to remind him that we're not young lads any more!"
Aside from the wicked humour that permeates dressing-rooms, Dunn also has fond memories of Sutton on the football pitch, as well.
Dunn spent only a small chunk of his Blackburn career in the same line-up as Sutton but did appear in a fixture that will instantly endear him to Birmingham supporters.
February 6 1999 will always be etched in Dunn's memory bank;l it was on that day that he scored his first goal as a professional footballer. But, unbeknown to him at the time, it was to earn him kudos among his future employers.
Dunn said, with a smile: "I made my debut when Chris was still at Blackburn and he played a part in my first goal, which was at Villa Park.
"We won 3-1 that day and Chris played well but you would expect that, as he is a good player.
"He is a strong fellow and good in the air. Another of his strengths is holding the ball
up and he is a clever player, who is a good finisher.
"You don't win the Premier League title for nothing and he was fantastic the year Blackburn won the Premiership.
"I can remember one of his goals where he did a step-over at the edge of box, which completely deceived a defender, before curling an unstoppable shot into the top corner. He was on fire that season and he is bound to give the whole club a lift."
The impending return of Dunn will also give Birmingham supporters a lift and the midfielder said he was in contention to face Charlton tomorrow.
Dunn's injury problems have been well documented after spending the best part of ten months out due to a back operation and problematic hamstrings.
He was hailed as the prodigal son on his return against Villa in October but his progress has been hampered by a thigh injury.
He has appeared on only eight occasions this season, his last outing being an 18-minute cameo at Tottenham on Boxing Day, yet he has shown glimpses of his undoubted talent.
He is optimistic that he will be able to play some part in Birmingham's final 18 games of the campaign.
"I feel sharp," Dunn said. "Obviously, I am a little bit away from full fitness. I will probably be playing in games but I am not half as fit as the other lads at present; I have missed a lot of football.
Meanwhile, Walter Pandiani's expected transfer to Espanyol was reported to have gone through last night.
A statement on the Primera Liga club's website said the Uruguay international will undergo a medical today, to complete the #1million transfer.
This will be Pandiani's third spell in the Spanish top flight following spells with Deportivo La Coruna and Real Mallorca. He rejected the chance to rejoin the Balearic island club earlier this month.
