Sheffield Wednesday got their season off to a good start on Sunday.
The Owls started the season as one of the favourites for promotion and got off to the perfect start, beating fellow Championship promotion rivals Aston Villa 1-0 at Hillsborough on Sunday.
Wednesday have got an exciting side with quality players such as Fernando Forestieri, Steven Fletcher and Barry Bannan, yet boss Carvalhal feels as a squad they are still short on numbers.
Speaking after his side’s win over the Villans, the Portuguese coach says he wants a miniumum of four new additions before the transfer deadline as he seeks promotion to the Premier League.
"We have a squad that is not complete, we have a team to start the competition, but we have some gaps," Carvalhal told Sky Sports.
“We need one more player minimum in midfield, we need a winger and left-back and we need a centre-back, so four players at minimum to complete the squad. It's easy to see where we have the gaps."
Daniel Pudil is Wednesday’s number one left-back, yet beyond the former Watford man there doesn’t appear to be too much competition and the same can be said in central defence.
Sam Hutchinson, predominently a holding midfielder, played the opening fixture alongside Tom Lees at cente-back and it only takes an injury or two to hand Carvalhal a major issue in defence.
Going forward the club are stocked with options and a good variety of players, but another holding midfielder to support Bannan and Kieran Lee could make a big difference in those tough away matches.
