Sunderland striker Steven Fletcher believes the club have improved under new manager Sam Allardyce despite their 6-2 drubbing by Everton at the weekend.
Allardyce, who replaced Dick Advocaat at the Stadium of Light last month, endeared himself to fans with a 3-0 win in the Tyne-Wear Derby last weekend but failed to build on that result, suffering a heavy defeat at Goodsion Park on Saturday.
Fletcher, though, believes Allardyce has had a positive impact on the squad and has called on the players to cut out the crucial mistakes that have seen them lose seven of their 11 Premier League games so far this season.
"We have improved, we are a lot more organised under this manager," the Scotland international told the Chronicle.
"He has us going into games with more confidence and it showed at Everton in the first 20 minutes. Had we scored our chances in those early moments we would have been 2-0 up and it would have been completely different.
"It was frustrating in the end. I think it is the silly mistakes that we need to cut out, massively. In the Premier League if you make one mistake then teams will pounce on you.
"We are creating chances though which is a good thing. Hopefully we can stop conceding so many and we will be alright."
