In fact Portsmouth could have stolen all three points but for a fine save by Spireites keeper Tommy Lee from Fogden.
Barker said: "We sat down and gave them a really specific job to do - and I must say I thought they were fantastic.
"Wes' energy is just so contagious. He covers so much ground, but so does Romain and he was a real goal threat in the first half.
"That was important because Jake Jervis could have become isolated up front on his own.
"But I thought the two advanced midfield lads - and Toumani Diagouraga just behind them as well - were excellent."
- Wes Fogden
- Romain Padovani
