Everton manager David Moyes is in no doubt where the chief threat will come from as Bolton visit Goodison Park on Wednesday - Kevin Davies.[LNB] The Wanderers captain is enjoying some of the best form of his career this season and was rewarded with a first England cap last month.[LNB]The 33-year-old, who scored twice in a stunning win over Tottenham last weekend, has long been viewed as a nuisance by opponents for his rugged approach but only now is he earning widespread plaudits.[LNB]Moyes, 47, has long been aware of Davies' attributes and can recall coming up against him during the latter stages of his own playing career in 1997. Moyes said: "Over the years we have known an awful lot about him.[LNB]"At the end of my career I think I played against him when he was at Chesterfield.[LNB]"So he's been around, he's seen a few clubs but I think he has been more appreciated over the last few years for what he can do as a team player.[LNB]"He is a big part of their game, they use him a lot. They get the ball up to him and gain free-kicks from him or flick-ons.[LNB]"They want to play as well but they have always got that get-out. He does it well for them.[LNB]"They are a high-energy team but a lot of their play is centred around Kevin Davies."[LNB]Moyes, however, does recognise how Bolton have improved since Owen Coyle took charge at the Reebok Stadium in January.[LNB]Coyle steered the Trotters clear of relegation from the Barclays Premier League last season and has overseen a fine start to the current campaign.[LNB]The Spurs victory left them sixth at the end of last weekend's action with 15 points from 11 games, one point more than Everton.[LNB]Moyes said: "I think there is an awful lot of similarity with Bolton as it has been nearly the same team over the last couple of years.[LNB]"The squad hasn't changed that much but I think there has been a development.[LNB]"Owen has done a great job. After rescuing Bolton a bit and making sure they stayed in the division, he has got them at the right end of the league."[LNB]Everton themselves have recovered after a poor start to the season which left them bottom after six games.[LNB]The Toffees are unbeaten in six games - a sequence which includes wins over Birmingham, Liverpool and Stoke - and are confident of improving upon last season's eighth place.[LNB]But Moyes still has concerns. He felt his side let an opportunity slip as they fell behind twice before claiming a 2-2 draw at Blackpool on Saturday and their inability to create and take goalscoring chances is a continuing problem.[LNB]He said: "We have got to try to get one or two added - we are desperately short of options up front.[LNB]"Maybe the final ball into the box hasn't been good enough to give those boys a chance as well.[LNB]"We have got to look at options to see if we can find ways of scoring more goals - that's what's missing.[LNB]"Overall our play has been good, our approach play has been good in nearly all the games but when we get 25 yards out we can just peter out a bit.[LNB]"Let's hope though we are just about to give someone a few goals' hiding."[LNB]Midfielder Marouane Fellaini could return having made a quicker than expected recovery from the hamstring injury suffered on international duty last month.[LNB]The Belgium international has missed the last four games.[LNB]"He is getting better and has got a chance," Moyes said. "He will be in the squad.[LNB]"He is back a week ahead of schedule, which is pleasing."
