Arsenal defender Kieran Tierney has hailed the season form of Bernd Leno.
Tierney heaped praise on Leno following his dramatic penalty save against Chelsea.
He told Sky Sports: "Leno has dug us out of a hole there as it would have been a long five minutes if that penalty had gone in.
"Leno is an outstanding keeper and he saved us."
The victory was Arsenal's first Premier League win since November 1.
