Landon Donovan has apologised to his Everton team-mates following his glaring miss in the defeat to Tottenham.
The America international wasted a great chance to earn Everton a point at White Hart Lane after missing an open goal late on after being picked out by Jack Rodwell at the far post.
Donovan admits he cannot fathom how he missed the gilt-edged opportunity, with Toffees team-mate Mikel Arteta revealing the loan signing from LA Galaxy issued an apology after the game.
"Landon said sorry to us afterwards," said Arteta.
Donovan noted: "This is just a really disappointing moment for me personally.
"I've put a lot into my time here and another goal would have been a nice reward.
"I got myself in a good position at the back post and was hoping Jack was going to put the ball across goal. He did that and it came perfectly for me.
"It's hard to understand what went wrong. I felt like everything was right but then I looked up to see the ball had hit the side-netting.
"It's so frustrating because if we had scored then it's possible we might have gone on to win the game.
"It's tough but we've got to put this behind us now and move on. There are still a lot of points to play for."
Everton boss David Moyes was encouraged by Phil Jagielka's return to the squad following his recovery from a serious knee injury.
Jagielka continued his comeback with a substitute appearance at White Hart Lane and Moyes is delighted to have the defender back in his plans.
"He made a massive difference when he came on against Spurs," Moyes said.
"On his day he's a really top defender. He's probably not ready for 90 minutes yet."
Moyes, when asked about Jagielka's England chances, added: "He was certainly in their views. If he plays like he did against Spurs he's not far away."
