Koeman ready to buy to find balance
Ronald Koeman was left with plenty of questions after Everton's slump continued with a 3-2 defeat by Watford on Saturday.
And the Toffees boss admits he may have to wait until next month's transfer window before he can find the answers.
Everton led through Romelu Lukaku's early strike, but were then blown away by Stefano Okaka's first goals for Watford, either side of Sebastian Prodl's header.
Lukaku pulled one back with five minutes remaining, but Koeman's side could not find an equaliser and have now won just one of their last 11 matches in all competitions.
"It's strange, and sometimes difficult to understand what happens," said the Dutchman.
"We started really well, we were confident on the ball, scored a good goal, and so it's really frustrating.
"Why did we lose control of the game? Why did we give belief to Watford, who at the time were nervous? That's my question.
"At 1-0 up, it should give us confidence. I'm really disappointed with the goal for 1-1.
"We conceded two from set- pieces and then showed a good reaction. But why always that reaction? We need to be more proactive, we are reactive and that's the problem.
"The Premier League is not always about football quality, it's about physicality and winning second balls and, in that aspect, the team is too weak.
"We have difficulties against direct, aggressive teams. In that aspect, we need to improve and do better and that's the big concern.
"You can't do that in two weeks, you need January and the summer. We need a better balance in our team."
Watford boss Walter Mazzarri praised two-goal hero Okaka, who has been a bit-part player at Vicarage Road since joining from Anderlecht in the summer.
"I've known Okaka since he was very young at Roma," said Mazzarri.
"He was a great talent then, so when we had the opportunity to sign him, we took it. He's perfect for the Premier League.
"He doesn't only help himself, he helps his teammates to play football and to score.
"It was great movement and the whole play that led to his first goal we have been practising all week.
"Okaka then did what only important players can do." - PA SPORT
