Pennington made his first appearance for Leeds yesterday, after signing on a season-long loan from Everton.
The centre-back came on as a second-half substitute, during Leeds’ 1-1 draw against Borussia Monchengladbach.
And Pennington was taken aback by how many Leeds supporters had travelled to watch the side on their pre-season tour.
The 23-year-old said: “Seeing this many fans in Austria for a friendly tells you what a good move this is.”
Leeds scored their goal against Monchengladbach through Luke Ayling, before the German side equalised in the second-half.
Pennington could have a key role to play for Leeds in the upcoming campaign, as Thomas Christiansen’s options at the back are still fairly short.
Leeds only have three centre-backs to pick from, with Pennington set to be in competition with Pontus Jansson and Liam Cooper for a place in the Whites’ starting line-up.
Leeds have one more game left on their tour of Austria, when they are set to take on Eibar.
