Luke Williams believes his overly aggressive tactics were to blame for Swansea's 5-0 FA Cup hammering at Bournemouth.

Williams, 43, was overseeing just his fourth game in charge of the Championship outfit having been poached from League Two side Notts County earlier this month.

But any hopes he had of his side upsetting their Premier League hosts rapidly unravelled during a disastrous first period which saw the Cherries run riot.

Strikes from Lloyd Kelly, Alex Scott and Luis Sinisterra effectively ended the tie within 15 minutes, with David Brooks and Dominic Solanke also netting before half-time.

Thankfully for the Welsh side, there were no further goals after the break and Williams accepted his setup had been too adventurous.

He said: "I apologised to the players as I tried to set up the team to cause a problem for the opposition. 

"Because it's a cup game we have to find a way to win the game. But I got the balance wrong.

"There weren't too many players in advanced positions and in the turnover, too few players to stem the attack — and our opposition were very good.

"It was very difficult to get near their goal and in the second half we tried to limit the damage because the scoreline was too heavy.

"The players were very nervous but I don't want to talk too much about individual errors. 

"We're playing against an outstanding team who we are most probably going to lose against because there's too much of a gap between the quality of the two teams at this moment in time.

"Individual mistakes were disappointing but I needed to help the team quicker and find a way to give them more bodies behind the ball to defend."

The Swans will now switch focus back to their second-tier campaign, where they currently sit nine points clear of the relegation zone and 10 points off the play-off places.

Meanwhile, Bournemouth find themselves in the last 16 of the FA Cup for only the third time since 1989.
