Bournemouth looked set for a frustrating defeat when Lucas Paqueta’s 87th-minute penalty put the Hammers ahead, the Brazilian converting coolly from the spot when Tyler Adams was ruled to have handled Aaron Wan-Bissaka’s cross after a VAR review.

After Antoine Semenyo and Jarrod Bowen struck the woodwork at either end during a frantic first half, West Ham was indebted to goalkeeper Lukasz Fabianski for making a string of excellent saves.

His most impressive stop came when he scrambled across his line to keep out Dango Ouattara, with Evanilson and Ryan Christie also denied as Bournemouth were kept at bay.

However, West Ham's resistance was broken in stunning fashion with stoppage time looming. On as an 80th-minute substitute for Evanilson, Unal picked out the top-left corner with a tremendous dead-ball effort from 25 yards out, earning his team a point.

The Cherries remain sixth in the Premier League table with 25 points, three adrift of the top four. West Ham, meanwhile, stay 14th with 19, seven clear of the relegation zone.

Having emerged as surprise contender for Europe, Bournemouth will hope the depth of its squad allows it to continue grinding out results.

Its eight goals via substitutes are the most in the Premier League this season, while three of Unal's four strikes in the competition have now come from the bench.

The point keeps the Cherries inside the Premier League's top six, just the second time they have ended a day in such a lofty position in the table at least 15 games into a season, previously doing so in December 2018 under Eddie Howe.
