Millwall back to winning ways with 4-2 Cup cracker at Watford
Ashlee Hincks and Fliss Gibbons gave the Lionesses a two-goal advantage by half-time and though Lennon got on the score-sheet in the second half, goals from Anneka Nuttall and Stacie Donnelly kept Watford in it.
Millwall's Jordon Butler suffered a knee injury that caused a lengthy delay late on, but Rinsola Babajide struck in stoppage time to secure a second away victory of the season for the Lionesses.
And captain Lennon said: "We've had a tough time of it lately, not necessarily getting the results or the performances that we want. We just wanted to come here, prove a point, get back to winning ways and get back to the performances we had at the start of the season.
"All the times we've played Watford they have given us a good game; it's always a nice feisty battle, which I think the fans enjoy as well.
"We've found goals hard to come by this year, so it's nice to score four and spread them around a bit."
Donnelly forced visiting keeper Frankie Gibbs into a clever save just before the break with a crisply struck shot from distance, but the Lionesses doubled their advantage moments later courtesy of a sublime curler from Gibbons after Hincks had laid the ball into her path.
Watford reduced the arrears in the 55th minute, with Nuttall rising brilliantly to head home a corner only for Millwall to restore their two-goal cushion just before the hour mark with a firm finish from Lennon.
However any hopes Watford had of clawing their way back on to level terms were quashed when Babajide came off the bench and wrapped it up for Millwall with a terrific solo effort in injury time.
Millwall's next match is at home to table-topping Doncaster Belles on Sunday 23rd August, with a 2pm kick-off at The Den. Buy your tickets here
