In the summer we had 3 very good options for keeper. No other side has regularly rotated keepers in my lifetime so it could be another RDZ master stroke. Bart & Steele both very capable with their feet and have slightly different strengths so as long as they are performing at the required level...
A keeper could get injured and the number two be asked to play regularly. This would keep them both match ready. I can also see an advantage to playing Sanchez against a big strong side who score from set pieces over Steele. Maybe Verbruggen offers something different to Steele
Maybe we thought West Ham offered more of an Ariel threat and that Bart was best to deal with that. I can't say either have given me any concerns during the 3 games so far and I'm certain Verbruggen is our long term plan
