Tommy Wright feels St Johnstone deserved spot-kick versus Celtic
St Johnstone manager Tommy Wright felt his side deserved a penalty kick in the 1-0 defeat to Celtic at McDiarmid Park.
Saints striker Stevie May went down in the box as he tussled with Virgil van Dijk but referee Craig Thomson was unmoved by the appeal.
"A couple of players not in the squad said they've seen it and they thought it was a penalty," said Wright.
"The referee's got a difficult job to do but it would've been nice to get that and possibly get a draw."
Van Dijk had earlier scored the only goal of the match, running from his own half and beating several players before scoring past goalkeeper Alan Mannus at his near post.
"We're really disappointed with the manner we lost the goal," Wright told BBC Radio Scotland.
"I think we put a lot into it. Celtic had the lion's share of the chances but I think we created enough chances to get something out of the game."
St Johnstone sit in sixth position in the Scottish Premiership, one point clear of Hibernian in seventh place.
