Sure he has the quality to do things here which is why you can't label him as a flop just yet. I mean Sheringham left the club as a complete success but after a year and a half was deemed to be even more of waste of space than some people have labelled Berbatov.
Dimitar can still turn it around but if he carries on performing as he has done (alright but not outstanding) and then gets sold in the summer, he would be deemed as a bit of a flop.
Not technically true that mate, Sheringham certainly had an indifferent first season at United (and you could say he was average for the whole of the second season, the Treble Year) but despite his limited goal scoring record, Sheringham did actually contribute and perform to a more consistent level than Berbatov has ever shown for us.
Sheringham was bought as a third striker in an intended rotation of Cole, Solskjaer and himself. Cole himself has been at United two and a half years and had been in and out the side since 1996 with injuries and loss of form for most of 1996-97.
Solskjaer was also in his second season and Ferguson was worried that given his excellent first year with us, he may suffer Second Season Syndrome. Sheringham was also 31 years old at the time of purchase, he was bought for experience and talent yet potentially as a stop-gap, nothing more.
Berbatov was bought as a 27 year old, one to make impact and as a thirty million quid-er, one to be thrust into the first team yet we have seen he is not considered in the big games.
Sheringham also scored some important goals for us, against Arsenal in the big title games back then, cup finals etc. Berbatov has scored one goal, a gratuitous tap-in versus a poor Chelsea side who sacked their manager afterwards, in the Big Four matches in his two years with us....so far.
He has to start doing a lot more, because otherwise those who are still defending the undefendable with his Match of The Day flicks and youtube compliations which seemingly justify his position at Man United will also lose faith soon....
