Gillingham manager Gareth Ainsworth’s praise for centre-half pair Sam Gale and Andy Smith after 1-0 win over Notts County

Gillingham’s ‘hard to beat’ mentality has delighted the manager - and they maintained their clean-sheet record on Saturday with an inexperienced centre-half pair.

Manager Gareth Ainsworth switched from a back five to a 4-2-3-1 formation, which meant Robbie McKenzie stepping back into midfield, leaving 20-year-old Sam Gale and Andy Smith, 24, at the heart of their defence, against a County side with an attacking line-up that few can match in League 2.

The Gills kept another clean sheet - their fourth in eight league games - to secure another win to stay joint top of the table.

“I don't think there was a younger pairing in the league (on Saturday),” said the manager.

“Wow, they're solid, really solid. I'm really proud that they've come up with a clean sheet and we did the business at the other end.

“The two centre-halves are the unsungs.

“Glenn's had one save to make, from distance, where the boy (Jodi Jones) ran through about four in midfield and sort of scuffed his shot. Apart from that, I don't think Glenn had a save to make. What a testament that is for the two young boys.”

Gale and Smith started the season among the substitutes but with Conor Masterson and Shad Ogie picking up injuries, the pair have secured a starting role in the side.

Ainsworth was an old-school winger as a player, that loved to take defenders on, but as a manager he enjoys coaching his team’s on keeping things tight at the back - leaving his assistant Richard Dobson to concentrate on their attacking threat.

He said: “It's amazing because I was an out-and-out forward and I loved attacking. My strength wasn't defending but maybe it was a little bit as well, because I'd win headers and tackles and things like that.
