Foreign XI
GK - Wilko De Vogt (NED).
I think we've only had 3 foreign keepers make 1st team appearances, the others being Frank Talia (AUS) infamous Lee Baxter (who was half Swedish). De Vogt. Talia and De Vogt both made 6 appearances and were equally unmemorable. De Vogt played in the Battle of Bramall Lane so can have a starting berth by virtue of that.
RWB - Vas Borbokis (GRE)
Easy choice. One of the few successful foreign signings we've made Absolutely made for the right wing back position. Struggled defensively in a 4-4-2. Only other foreign right backs I can think of is Lescinel Jean François (HAT) and David Sommeil (GUA).
LWB - Roger Nilsen (NOR)
Possibly the only foreign left back we've ever had.
CBS
Michael Vonk (NED), Shaun Murphy (AUS), Claude Davis (JAM)
Slim pickings in this department. Murphy probably the most fondly remembered. "Cut throat" Davis gets in by virtue of playing in the Premier League although made some horrendous errors.
The only others I could think of are Doug Hodgson (AUS) who was mainly a reserve (albeit a colourful character), Jonas Wirmola (SWE)(played a handful of games) and Davy Gysbrechts (BEL) (largely a sub in the Adrian Heath era). Tri Dellas (GRE) may have been a shout but was mainly used as a CM.
CM
Sander Berge (NOR), Alex Sabella (ARG), Colin Kazim Richards (TUR)
Again not much competition in this department. I'm too young to have seen Sabella but is arguably our greatest ever foreign player. Kazim Richards played in the Prem weighing in with a few goals. Berge hasn't put in many great performances but when he has he's looked head and shoulders above anything we've seen in my lifetime.
CF
Jan Aage Fjortoft (NOR), Lys Mousset (FRA)
Fjortoft is self explanatory. Whilst most fans would now be happy to see Mousset moved on he was virtually unplayable at times last season and was a key part of the side finishing 9th in the first season back in the Premier League.
SUBS
Talia (AUS), Dellas (GRE), Santos (SUR), Marcelo (BRA/POR), Peschisolido (CAN)
