Derby County confirm Wigan Athletic goalkeeper swoop
He kept 15 clean sheets in 39 appearances - including a jaw-dropping run of 10 shut-outs in 11 matches during the run-in.
“We’re really pleased to welcome David to Derby County," said Rams boss Phillip Cocu.
“David is an experienced goalkeeper and he has played at the highest level in both England and Scotland.
“He has also performed at international level for Scotland, and I believe David will be a positive addition to not only our goalkeeping department but also our squad.”
