Weir strengthens with quartet
Barcelona midfielder Andres Iniesta would be happy to sign an extended contract which would see him end his career at Camp Nou.
The 29-year-old Spain international believes that there is already a willingness from both parties to ensure that his current deal, which runs to 2015, will be renewed soon.
Iniesta made his first-team debut over a decade ago and has become an integral member of the Blaugrana side which has gone on to become one of the most feared and respected in Europe.
"It is my dream to end my career at Barcelona. Nothing has changed in that regard. We will see how it all unfolds, but I do not expect any problems with my contract renewal," Iniesta told Sport.
"When both parties have the intention to continue together, the renewal should be done pretty quick.
"In the situation I find myself in, everybody in the world would want to be rewarded fairly. You have to give it good thought and make a decision.
"When we sit down and open talks, I hope it will be resolved quickly because we both want the same thing."
The 22-year-old, who scored five goals in 45 appearances for the Pilgrims last season, has agreed a two-year contract at Adams Park.
Manager Gareth Ainsworth told the club's official website: "Paris is a player we've been watching for a while and he impressed in both games against us last season.
"He's quick and tricky and will add another dimension to our attack. I'm sure he's a player that our fans are going to enjoy watching.
"I'm delighted he's agreed to join us and I'm looking forward to working with him."
Cowan-Hall, who came through the ranks at Portsmouth before spells with Grimsby, Scunthorpe, Rushden and Woking, added: "It was a no-brainer for me and it's somewhere I'm wanted as well."
"He (Ainsworth) told me the ethos and what the boys were like. Wycombe won in Plymouth last season and I know the guys work hard.
"He told me the way he wanted to play and he wants to play football - it was an easy sell!"
Brandy, Stephen McGinn, Sean McGinty and Jasper Johns have all been unveiled at Bramall Lane as Weir begins to shape his squad for the forthcoming League One campaign.
Striker Brandy, who scored seven times for Walsall last season, has signed on a two-year contract along with versatile Scotsman McGinn who scored against the Blades last season while on loan from Watford at Shrewsbury.
McGinty, 19, has also penned a two-year deal having departed Manchester United.
Another player to leave the top flight is ex-Everton midfielder Johns who has signed a one-year deal and will begin in United's development squad.
New boss Weir told the club's official website: "We are delighted that deals for all four of the lads have been completed in time for them to start pre-season training with the rest of the squad and we are confident that we can develop their talents, individually and collectively, for the benefit of Sheffield United."
The Blades have retained the option to extend all four contracts for a further year.
