Graeme McDowell believes Tiger Woods is in the form to end his five-year major drought at the Open Championship this weekend.
The Northern Irishman played the opening two rounds at Muirfield with the world No 1, who combined superb putting with "devastating" iron play in rounds of 69 and 71 which left him well in contention on two under.
McDowell matched Woods' second-day 71 to remain comfortably inside the cut mark on four over, and he admitted his playing partner could be tough to beat come Sunday evening.
"He was very, very impressive the last two days. He will not be far away this weekend the way he's playing," said McDowell.
"He just hits the shot that you're supposed to hit at all times. Really, it's like, 'do I have to follow that?' He's so impressive. It's very difficult to focus on your own game when you're watching the best player maybe ever over the last two days.
"I lost count of how many comebacks he made for pars. He's putting them exceptionally well. He's playing the golf course very conservatively, using his iron play to devastating effect - very impressive.
"Combine that with some great putting, he's going to be dangerous. He certainly looks like he's very close to being back. So there will be no surprise to me if he's picking up the Claret Jug on Sunday night."
McDowell birdied the second and ninth in a battling outward 34, and although he flirted with the cut line after dropping three shots in five holes after the turn, he refused to rule out his own chances of Open glory.
"But I'm not writing off the rest of the field. There's quality players there in this field, and I'm certainly not writing myself off.
"The big key for me on Saturday is to get out there and get focused on my own game, try to shoot four or five under par and - who knows - I might have a shot come Sunday afternoon."
