Wigan manager Roberto Martinez has been happy enough with Wigan's pre-season efforts, but is keen to sign up more new recruits before the summer transfer window closes shut on the Latics.
Villarreal provided Wigan with their fifth summer victory on Sunday, and Martinez was heartened by the performance of his players at the DW Stadium.
"It's fair to say it's been a very intense pre-season, and I'm delighted with the manner in which the players have approached their work," said the Spaniard. “We've had three very different environments, and they've all been enjoyable and very rewarding.
"Sunday's game was the perfect way to end our preparations and get us ready for the hard work that starts next Saturday.
"Villarreal are a great side, very cute, and a great example of how to play between lines, and as a result, our concentration levels had to be maintained throughout which I was very happy with."
Wigan face newly-promoted Norwich City, Swansea City and QPR in their opening three Barclays Premier League matches, but Martinez has some work to do in the transfer market before taking on the first big test in September against Manchester City.
"As everyone knows we have lost Charles (N'Zogbia), Tom (Cleverley) and Mauro (Boselli), and that means we are light in numbers," the Latics boss continued.
"Obviously we need to replace them, and we are going to work as hard as we can over the next three weeks to make sure we bring the right characters into the club.
"But to be talking about new signings now is completely wrong - we need to be talking about the group of players we already have here that we are constantly trying to help."
