David Pleat was reminded on Saturday of how even a player, now regarded as being at the top of his game, still needed a significant period of time to adapt to the Premiership.
While our acting manager is regular fielding questions on the progress of recent imports Helder Postiga and Stephane Dalmat, David's memory was jogged by Arsenal boss Arsene Wenger that the prolific Thierry Henry took a good while to find his feet after arriving from Juventus.
Of course, the French international now features in the 'dream team' of many a pundit, but was the target of some initial sniping for his goalscoring record.
"Managers sometimes remind you of things and Arsene reminded me that when Thierry Henry came to this country he struggled for the first six months," said David.
"You have to take that on board when anyone criticises any of the new players - particularly foreign players.
"Dalmat and Postiga need time. The more they get a good feeling for the language and mixing with the other players the better they will get."
