The lads were dejected after the 5-1 loss against Chelsea at Wembley on Sunday.
They've had little time to reflect though with the crucial final five games of the Premier League upon us, kicking-off at QPR on Saturday.
"We all get very low but we came in on Monday morning and start again, you have to," said Harry before training on Friday.
"By the end of the week it’s history and you look forward to the next game.
"To be honest the players have looked sharp this week. Yesterday they worked fantastic. They zipped the ball about and it was a pleasure to be out there.
"We did lots of stuff on team shape but the quality of the play was top class and they look bright so hopefully we can carry that in to the weekend. We’re ready to go again."
We go into the weekend sitting fourth in the table as we scrap it out with Arsenal, Newcastle and Chelsea for a place in the top four and Champions League qualification.
It's a big weekend as Arsenal play host to Chelsea in Saturday's early kick-off, Newcastle then face Stoke at home and we travel to QPR for a 5.30pm kick-off.
"I still think we will finish fourth," stated Harry.
"We hopefully might finish third. There are five games to go and we have to think about winning all our games if we can.
"Newcastle, Arsenal and Chslsea are in the same position. It's all to play for."
