Chelsea midfielder Lesley Ugochukwu spared manager Enzo Maresca's blushes in his first game as manager by equalising late on against League One Wrexham in Santa Clara, California.
A sharp finish in the penalty box from Christopher Nkunku opened the scoring in the 35th minute of Chelsea's opening friendly on their pre-season tour of the United States.
But Wrexham took a surprise lead after both teams made wholesale changes at half-time with Luke Bolton and Jack Marriott scoring following defensive mistakes.
Ugochukwu equalised in the 82nd minute as Wrexham impressed - adding to their 1-1 draw against Bournemouth on Saturday in a half-empty Levi's Stadium, home of the San Francisco 49ers.
