Nigel Clough’s side got the better of Sunderland 2-1 at the Pirelli Stadium in League One on Saturday afternoon.
Jamie Allen and Kyle McFadzean were the goalscorers for the home team, while Chris Maguire found the target for the visiting side.
Burton goalkeeper Evtimov, who recently joined the League One club after leaving Championship side Nottingham Forest, has taken to Twitter to give his reaction to the win for his team.
The 25-year-old Bulgarian goalkeeper has also sent a message to Sunderland striker Charlie Wyke with whom he collided in the 43rd minute.
The 25-year-old striker joined Sunderland from Bradford City in the summer transfer window for a fee reported by The Northern Echo to be worth £1 million.
Sunderland are fourth in the League One table at the moment with 15 points from eight matches, while Burton are currently 14th in the standings with 10 points from eight games.
Really happy with the win today! Not an easy debut against strong Sunderland side, but the boys did really well and fought till the end! I hope that the injury of the Sunderland player I had a collusion with, it’s not bad and wish him a speed recovery! @burtonalbionfc— Dimitar Evtimov (@DimiEvtimov) September 15, 2018
