London Welsh assistant coach Ollie Smith admitted fly-half Shane Geraghty took the game away from his side in the first half, after they went down 50-12 at home to London Irish.
The 28-year-old Irishman pulled the strings in the midfield, adding eight points from the boot to his two scores as Irish ran in six tries before half-time in the battle of the Exiles.
Winger Alex Lewington nabbed his second Aviva Premiership Rugby hat-trick of the season, while Tom Fowlie, Matt Parr and Andrew Fenby also got on the scoresheet.
Welsh responded with tries from James Tincknell and Taione Vea, but Smith could only stand back and applaud Geraghty’s virtuoso performance before he was replaced at the interval.
“Shane Geraghty ran the show,” he said. “He's an outstanding player and he is very astute and I only wish we had him in our ranks.
“This was a good chance for us against the side above us but you can't go in at half-time 38-7 down.
“It left us far too much to do and all we could do was to try and win the second half.
“We didn't look after the ball, and when we gave the ball away it was catastrophic. However at least we salvaged something after the interval.
“We've not achieved what we wanted to so far this season but we are not giving up.”
Meanwhile Irish coach Glenn Delaney was thrilled with the resounding victory, despite his side losing some of the momentum after making a series of changes after the first-half.
It sees the Madejski outfit jump ahead of Newcastle Falcons in the standings and bounce back after two consecutive Aviva Premiership Rugby defeats.
Delaney said: “We were determined to give them a lot of respect and in the first half we were very clinical and really sharp.
“We scored tries from all aspects of our game which was very pleasing.
“We decided to take some of key players off at half-time as we want a depth in our squad and it's important that certain players have game time.
“We wanted to treat the second half like a new game with some different players, but it did become very fragmented.”
