Costel Pantilimon has continued to impress after being brought into the Sunderland line-up, helping his side to a 0-0 draw against Leicester City.
The Romanian stopper was in fine form yesterday as he thwarted Leicester's attack on numerous occasions and preserved a point for his side in what was a crucial match.
Pantilimon was signed from Manchester City this summer and he has had to bide his time to be handed a chance.
After a series of mistakes from usual first choice Vito Mannone, though, the towering custodian was selected and he has seized his opportunity with both hands.
Mannone won the club's player of the season award last campaign, but he faces a big fight to win his place back in the team and looks set for a lengthy spell on the sidelines unless Pantilimon's form goes rapidly down-hill.
It is a run of form which has pushed them away from the bottom three and Poyet's men will be hoping to continue to put space between them and the drop-zone.
They do have a tough set of fixtures coming up, but optimism is growing at the Stadium of Light and Pantilimon has played a major part in this.
Here is the best reaction from Sunderland fans on Twitter to the goalkeeper's most recent excellent performance.
@YoungSunEcho Pantilimon made some important saves. He's justifying dropping Vito at the minute.— Stephen Wallbank (@WallbankStephen) November 23, 2014

But good to see Costel Pantilimon getting a run of games - didn't spend much time in his company but always seemed like a good man.— Mark Booth (@markbooth_mcfc) November 22, 2014

Pantilimon another decent game calming influence at the back which in time will give players in front of him confidence to get frward #safc— SAFC TONY (@deacy72) November 22, 2014
Pantilimon, Reveillere, O'Shea, Catts, Johnson and Fletcher played well. Promising, at least.— Gav (@GavinSAFC) November 22, 2014
