Jermain Defoe scored five times in an incredible second half but Redknapp was keen to praise the contribution of England midfielder Lennon.

"I thought we started really bright, we had 25 minutes where we really got off after them in the first half before they came back into it," Redknapp told Sky Sports News.

"We came in at half-time and said we had to get back to how we started, pressing them all over the park, and we decided to work them and made the opportunities and took them.

"Their keeper (Chris Kirkland) made some great saves as well.

"Lennon is a fantastic talent, anybody would have had a hard day with him in that sort of form. He deserved that goal at the end."

Speaking about Defoe, Redknapp added: "For Jermain to get five goals was an outstanding performance.

"Yesterday in training he looked so sharp and I felt if he could carry that into the game he would be a real handful.

"You don't get too many nines in the Premier League, it's a bad day for Roberto Martinez but he'll come back even stronger and I'm sure next week he'll take it out on someone else."

Wigan boss Martinez said: "We finished the first half very strongly and looked like a team who were going to dictate things.

"But we have ourselves to blame for the goals we conceded and after that you are climbing a mountain."

The Latics' next Barclays Premier League match is next Saturday, when Sunderland are the visitors to the DW Stadium.

"We have to make sure we move on from this," Martinez added.
