Marco Silva admitted he hasn't yet got the answers to understand why Watford have dropped 10 points in the final 15 minutes of games this season - but felt the Hornets should have put the game to bed before their late capitulation against Swansea this afternoon.

Two late goals condemned the Hornets to a fifth defeat from six when they had looked set to go eighth in the table at the end of their final game of 2017.

And while Silva declined to refer to Andre Gray by name, it was clear it was the record signing's miss seconds before Jordan Ayew's equaliser which irked him the most about how the Hornets had failed to put the game beyond Swansea, and add to Andre Carrillo's 11th-minute opener.

He said: "It’s our job to find out why we cannot kill games off. It’s clear, we have to put the ball in the net.

"We made enough chances, the game was under control and the opponent didn’t create chances to put us in danger until then. We needed to score a second goal. We needed to be assertive."

The Hornets fans made their feelings known when the Hornets trudged off at full-time, and the head coach made clear he understood their anger with yet another capitulation.

He said: "I'm very disappointed for us. I’m disappointed for our fans as well.

"We did enough to win the game, our opponent had one shot on target from Ayew, but after that they didn’t create a chance until they equalised.

"Heurelho Gomes didn’t make a save until then, and we had enough chances to win the game and kill it off.

"We had a clear chance just before then, and at this level when you don’t score it gives the opponent some belief.

"We didn’t create a big number but there were enough. They won a second ball, and even after that we needed to keep focused.

"It’s a big mistake, our players didn’t stay focused until the end and we were not in position."
