Crewe manager Steve Davis predicts that new striker Mathias Pogba will prove a 'nuisance' to League One defences.
Pogba, elder brother of ex-Manchester United midfielder Paul, hit 12 goals for Wrexham last season before leaving to join the Alex on a two-year deal.
"What we wanted was a big, powerful, quick, young centre-forward who can run in behind and cause defences no end of problems," Davis told BBC Radio Stoke.
"He's basically just a nuisance but he's got quality," added the Alex boss.
"There are times when you need that type of player.
"We can go direct in the later stages of games and he can challenge in there."

on Mathias Pogba
“We will try and make him a bit more clever in front of goal and improve him in terms of his link-up play”
Pogba, who has been scoring regularly in Crewe's pre-season games, looks set to make his official club debut in Saturday's League Cup first round opener against Hartlepool.
And, although the bulky 6ft 1 in striker will make a contrast with the man he replaces in the Alex front line, last season's top scorer Nick Powell (their £3m-plus Manchester United signing), Davis has high hopes of Pogba.
"We will try and make him a bit more clever in front of goal and improve him in terms of his link-up play and in keeping the ball up there," added Davis.
Frenchman Pogba actually began his career in Spain in the youth team at Celta Vigo before moving to the fourth tier of French football with Quimper.
He signed for Wrexham in 2010 after impressing in a series of reserve games, going on to score 15 goals in 66 games.
The 21-year-old was offered a new deal to remain at the Racecourse Ground, where his contract had expired.
But Pogba has opted to move up two divisions in a deal which also has the option of a third year and includes a compensation payment to Wrexham, as he is under 24.
