The manager said it was important to look at the 'whole picture' and insisted he still believes we'll finish third.
In the three defeats we led 2-0 at Arsenal before the Gunners turned it around with two goals in as many minutes just before half-time.
We dominated the first hour against Manchester United last weekend but conceded a goal on the stroke of half-time and eventually went down 3-1 at the Lane.
It was a similar story at Goodison Park as we controlled the second half on this occasion but couldn’t convert possession and efforts on goal into goals.
Despite the three defeats, we’re still sitting third in the Premier League.
“We have to keep going,” said Harry. “I said that Arsenal beat us fair and square and we got what we deserved, nothing.
“Last week, we played ever so well against United, I felt it was unfortunate and again I thought we were very unfortunate at Everton - that’s football.
“We’ve won games that we shouldn’t have this year and you lose some that you shouldn’t lose.
“That’s the way it goes but you can’t just look at a result and say that was rubbish or that was good, you have to look at the whole picture.
“I couldn’t have asked for more in the second half at Everton, to dominate them like we did. We just needed a break in front of goal.
“We missed a chance at the end that 99 times out of 100 we would have scored. It was just one of those things.
“I said all along that 10 points can evaporate very quickly and I looked at the fixtures and knew going away to Arsenal, United at home, Everton and then Chelsea away, they are all tough games.
“We are still in a better position than the other teams so we have to keep going, keep believing and we will turn it around. We will go again.
“It’s difficult trying to finish above teams like City, United have been there and done it every year, Arsenal are in the Champions League every year.
“It’s a tall order to finish above these teams but I still think we will finish third.”
