Toby Sibbick believes AFC Wimbledon’s lapses of focus and concentration in “key moments” have cost them against the bigger teams in League One.

The Dons have only won twice against the division’s top half teams are winless against its top six clubs so far this season.

They are travelling to face relegation-threatened Rochdale next on Tuesday midweek but host a Lyle Taylor-led Charlton Athletic in his first return to the Kingsmeadow.

Sibbick was asked why Wimbledon’s performances in cup and league competitions have differed, and whether they “tail off” in League One, but he said: “I wouldn’t necessarily say that in the league things have tailed off. I’d say when we went up to Sunderland we matched them but yet again there was a lapse of concentration which cost us the game.

“I think, again, in big, key moments, that’s when we lack our focus, that’s where games are won and lost against the bigger teams in League One.

“I think we’re going to have to wait and see but I’ve got full faith in the lads in the dressing room that we’re going to get out of this.”

Three points are vital for the Dons in their fight to survive relegation as they are seven points adrift of safety with 14 games to go.

The surprise win at Walsall will improve circumstances, however, they will also be reliant on other teams around them failing to accrue wins themselves.

Asked whether Wimbledon could survive relegation, Sibbick added: “I think we can. Hopefully we have the confidence from Tuesday [against Walsall] to put in a performance.

“We just take it one game at a time.

“Once we get a run of results going, why can’t we? I think on our day we can beat anyone, we just need to get our heads on it.”
